Plant Sciences (BS)
College of Agriculture and Life Sciences
Program Description
The program in Plant Sciences helps students understand how plants work from the molecular to ecosystem level so graduates can make new discoveries in the lab and field, produce enough food for a growing world population; breed plants to tolerate the heat- and drought-stress of climate change; develop sustainable cropping practices to produce healthful and nutritious food; investigate new methods to fight disease; and transform sterile urban environments into vibrant microcosms of nature.
Plant Sciences courses are taught by faculty in the School of Integrative Plant Science, which is the administrative home for the Sections of Horticulture, Plant Biology, Plant Breeding and Genetics, Plant Pathology and Plant-Microbe Biology, and Soil and Crop Sciences. Together, they represent one of the strongest groups of plant scientists in the world. Students in the program share a common interest in learning about topics associated with plant growth and development in the broadest sense, but beyond that common thread, individual career goals vary widely. Some have their sights set on careers in applied agriculture or teaching, others plan to contribute to advancements of our knowledge through research, and still others see study in plant science as a stepping-stone to specialized training in business, government, law or medicine.
Almost 150 courses that deal directly with some area of plant science are offered in the School of Integrative Plant Science. There are also opportunities to engage in internships, undergraduate teaching, and research experiences. Students expecting to go on for a graduate degree are encouraged to participate in one or more of those experiences. Students who are planning to enter the workforce immediately upon completion of the B.S. degree are encouraged to obtain practical experience. This may involve summer employment in field research or in a plant production or maintenance-related industry such as a lawn and tree care company, commercial greenhouse, nursery, orchard, vineyard or winery, botanical garden or arboretum, crop production farm, or with Cooperative Extension.
In addition to classrooms and laboratories in five buildings on the Cornell campus proper, research and teaching facilities adjacent to the campus are available to students for hands-on practice, technical training, independent research projects, and internships. These facilities include research orchards and vineyards, golf courses and a turf research facility, the Cornell Botanic Gardens (including an arboretum and thousands of acres of natural areas), and vegetable and field crop farms. Demonstration/research facilities in Aurora (Cayuga County), Geneva (Ontario County), Highland (Ulster County), Lake Placid (Essex County), Middletown (Orange County), Odessa (Tioga County), and Riverhead (Suffolk County) are also available for undergraduate and graduate field study.
For more information about this major, see program webpage.
Academic Standards
- All courses in the Plant Sciences major are offered at the Ithaca campus unless otherwise noted. Online certificate or distance-learning courses, including those offered through Cornell, may not be counted towards major requirements.
- Students are expected to attend all required class activities in person.
- There is no minimum passing grade for courses required in the Plant Sciences major, but all courses used towards the major must be taken for a letter grade if the course is not S/U only.
- Courses may not be used to fulfill more than one major requirement.
Plant Sciences Policies
Students are expected to satisfy all degree requirements and comply with the following program policies. Any deviation must be petitioned prior to the act. Failure to comply with any program policies or petition decisions may result in review by the College Committee on Academic Achievement and Petitions.
Academic Standards
Students are expected to make continuous progress towards completing major requirements in the plant sciences. Students who do not enroll in classes required for the plant sciences major or fail to make adequate progress towards the plant science degree are not considered to be in good standing within the major. Students may simultaneously be in good standing with the college but not in good standing with the major.
To be in a good academic standing, a student must:
-
Successfully complete PLSCI 1101 – Plant Science and Systems in their first fall and PLSCI 1420 – Functional Plant Biology in their first spring.
-
Successfully complete PLSCI 2410 – Introductory Plant Diversity and Evolution in their second fall and PLSCI 2430 – Ecology and Evolution of Plants in their second spring.
-
Successfully complete a foundational course each semester of their third year.
Advanced Placement Credit
The general college advanced placement credit policies apply, in addition to the Plant Sciences specific policy below:
-
AP, IB, and GCE credit in Biology is not accepted to fulfill the introductory biology requirement.
-
AP, IB, and GCE credit in Chemistry is not accepted to fulfill the general chemistry requirement.
-
An AP Statistics score of 5 may be used to fulfill the statistics requirement.
Study Abroad
Plant Sciences majors are encouraged to go abroad at some point during their time as a student. Study abroad is an option to consider since the curriculum is designed to be very flexible. It is not necessary to take courses abroad for Plant Sciences major requirements. While abroad, it is more desirable to take courses that reflect the region you are in since plants are everywhere.
If you do want to bring back one or two courses for major requirements, the Plant Sciences Curriculum Committee (PSCC) will consider those on a case-by-case basis. A current and complete syllabus must be submitted with the petition for each such course; and if you take the course before approval is given, you should not assume that the course will satisfy major requirements.
Double Major
Cornell students are not allowed to double major across colleges. Students are not allowed to continue their studies past their eighth (or equivalent) semester to complete additional majors or minors. Students who pursue a second major must choose a major within the College of Agriculture and Life Sciences.
Plant Sciences students can double count a maximum of 12 credits between their two CALS majors. The introductory disciplinary courses (biology, general chemistry, organic chemistry, and statistics) are allowed to be shared between programs and do not count towards the 12-credit maximum.
CALS students who fit one or more of the following conditions are ineligible to double major in Plant Sciences:
-
Current juniors or seniors
-
Agricultural Sciences majors
If you do not qualify for the Plant Sciences double major, consider adding a SIPS minor, particularly the Plant Sciences minor.

University Graduation Requirements
Requirements for All Students
In order to receive a Cornell degree, a student must satisfy academic and non-academic requirements.
Academic Requirements
A student’s college determines degree requirements such as residency, number of credits, distribution of credits, and grade averages. It is the student’s responsibility to be aware of the specific major, degree, distribution, college, and graduation requirements for completing their chosen program of study. See the individual requirements listed by each college or school or contact the college registrar’s office for more information.
Non-academic Requirements
Conduct Matters. Students must satisfy any outstanding sanctions, penalties or remedies imposed or agreed to under the Student Code of Conduct (Code) or Policy 6.4. Where a formal complaint under the Code or Policy 6.4 is pending, the University will withhold awarding a degree otherwise earned until the adjudication process set forth in those procedures is complete, including the satisfaction of any sanctions, penalties or remedies imposed.
Financial Obligations. Outstanding financial obligations will not impact the awarding of a degree otherwise earned or a student’s ability to access their official transcript. However, the University may withhold issuing a diploma until any outstanding financial obligations owing to the University are satisfied.
Additional Requirements for Undergraduate Students
The University has two requirements for graduation that must be fulfilled by all undergraduate students: the swim requirement, and completion of two physical education courses. For additional information about fulfilling University Graduation Requirements, see the Physical Education website.
Physical Education
All incoming undergraduate students are required to take two credits (two courses) of Physical Education prior to graduation. It is recommended they complete the two courses during their first year at Cornell. Credit in Physical Education may be earned by participating in courses offered by the Department of Athletics and Physical Education and Cornell Outdoor Education, by being a registered participant on a varsity athletic team, or performing in the marching band.
Students with medical concerns should contact the Office of Student Disability Services.
Swim Requirement
The Faculty Advisory Committee on Athletics and Physical Education has established a basic swimming and water safety competency requirement for all undergraduate students. Normally, the requirement is taken during the Fall Orientation process at Helen Newman Hall or Teagle Hall pools. The requirement consists of the following: jump or step feet-first into the deep end of the pool, float or tread for one minute, turn around in a full circle, swim 25 yards using any stroke(s) of choice without touching the bottom or holding on to the sides (there is no time limit) and exit from the water. Students who do not complete the swim requirement during their first year, during a PE swim class or during orientation subsequent years, will have to pay a $100 fee. Any student who cannot meet this requirement must register for PE 1100 Beginning Swimming as their physical education course before electives can be chosen.
If a student does not pass the swim requirement in their first Beginning Swimming PE class, then the student must take a second Beginning Swimming PE class (PE 1100 or PE 1101). Successful completion of two Beginning Swimming classes (based on attendance requirements) with the instructor's recommendation will fulfill the University's swim requirement.
Students unable to meet the swim requirement because of medical reasons should contact the Office of Student Disability Services. When a waiver is granted by the Faculty Committee on Physical Education, an alternate requirement is imposed. The alternate requirement substitute is set by the Director of Physical Education.
CALS Graduation Requirements for the Bachelor of Science

Distribution Requirements
The purpose of the distribution requirement is to have all students achieve common learning outcomes. It is expected that through college and major course requirements graduates will be able to:
- Explain, evaluate, and effectively interpret factual claims, theories, and assumptions in the student’s discipline(s) (especially in one or more of the college’s priority areas of Food & Energy Systems, Social Sciences, Life Sciences, and Environmental Sciences) and more broadly in the sciences and humanities.
- Find, access, critically evaluate, and ethically use information.
- Integrate quantitative and qualitative information to reach defensible and creative conclusions.
- Communicate effectively through writing, speech, and visual information.
- Articulate the views of people with diverse perspectives.
- Demonstrate the capability to work both independently and in cooperation with others.
Through the study of Physical and Life Sciences, students develop their understanding and appreciation of the physical sciences, enhance their quantitative reasoning skills, and gain an appreciation of the variability of living organisms. Social Sciences and Humanities gives students perspective on the structure and values of the society in which we live and prepares them to make decisions on ethical issues that will affect their work and role in society. Written and Oral Expression is designed to help students become competent and confident in the use of oral and written communication to express themselves and their ideas.
Important Notes:
- Credits received for independent study, fieldwork, teaching, research, work experience, and internships cannot be used to fulfill the distribution requirements

Transfer students may have non-Cornell courses that meet SUNY World Languages requirements and are a minimum of three (3) credits reviewed as fulfilling FL-AG.
Human Diversity (D-AG)
These courses analyze historical or contemporary marginalized communities and the culturally specific contexts that produce unequal power relations in terms of race, nationality, ethnicity, indigeneity, sexuality, disability, religion, gender, or economic status.
Definition of “marginalize”: Any groups with reduced access to social status, political influence, economic advancement, educational advancement, healthcare, information, or any of the goods, services, and powers of a society can be considered “marginalized.” Causes of marginalization may be related to ethnic status, religion, country of origin, sexual orientation, geography, economics, and government policies. Those who exist on the furthest margins of a society are frequently subject to several of these forces.
CALS also accepts courses of at least three (3) credits with the following distributions as fulfilling D-AG: SCD-AS, SCD-HA, D-HE.
Non-equated external transfer courses will only be considered for junior transfer students who have taken an appropriate course at their prior institution and whose schedule does not allow space to take a Human Diversity (D-AG) course at Cornell. These situations will be reviewed individually after a required appointment with CALS Student Services.
Historical Analysis (HA-AG)
These courses interpret continuities and changes—political, social, economic, diplomatic, religious, intellectual, artistic, scientific—through time. The focus may be on groups of people, dominant or subordinate, a specific country or region, an event, a process, or a time period.

Courses investigating the sources, structure, and limits of cognition may use the methodologies of science, cognitive psychology, linguistics, or philosophy. Courses focusing on moral reasoning explore ways of reflecting on ethical questions that concern the nature of justice, the good life, or human values in general.
CALS also accepts courses of at least three (3) credits with the following distributions as fulfilling KCM-AG: ETM-AAP, ETM-AS, ETM-HA, KCM-AAP, KCM-HE
Literature and the Arts (LA-AG)
These courses explore literature and the arts in two different but related ways. Some courses focus on the critical study of artworks and on their history, aesthetics, and theory. These courses develop skills of reading, observing, and hearing and encourage reflection on such experiences; many investigate the interplay among individual achievement, artistic tradition, and historical context. Other courses are devoted to the production and performance of artworks (in creative writing, performing arts, and media such as film and video). These courses emphasize the interaction among technical mastery, cognitive knowledge, and creative imagination.
CALS also accepts courses of at least three (3) credits with the following distributions as fulfilling LA-AG, ALC-AS, ALC-HA, ALC-AAP, LA-AAP
Social and Behavioral Analysis (SBA-AG)
These courses examine human life in its social context through the use of social scientific methods, often including hypothesis testing, scientific sampling techniques, and statistical analysis. Topics studied range from the thoughts, feelings, beliefs, and attitudes of individuals to interpersonal relations between individuals (e.g., in friendship, love, conflict) to larger social organizations (e.g., the family, society, religious or educational or civic institutions, the economy, government) to the relationships and conflicts among groups or individuals (e.g., discrimination, inequality, prejudice, stigmas, conflict resolution).
CALS also accepts courses of at least three (3) credits with the following distributions as fulfilling SBA-AG: SSC-AS, SBA-HE, SBA-AAP, SSC-AAP
Written and Oral Expression:

Written Expression (WRT-AG)
All students are required to take at least six (6) credits of Written Expression and may take nine (9) credits to fulfill the Written and Oral Expression requirement. Courses that fulfill the Written Expression requirement in CALS focus on enhancing students’ writing skills. Courses meeting this requirement devote at least 50% of class time to writing proficiency, involve at least five (5) writing assignments with detailed feedback, and emphasize revision and development. These courses ensure personalized attention and help students articulate ideas clearly, argue effectively, and engage with evidence critically. This structure supports students in improving both their writing mechanics and their ability to communicate persuasively across contexts.
CALS also accepts FWS courses as fulfilling WRT-AG. Transfer students may have courses that meet the SUNY Writing Requirement considered to fulfill this requirement.
Oral Expression (ORL-AG)
Students may take one (1) Oral Expression course towards the nine (9) required credits for Written and Oral Expression. Courses that fulfill the CALS Oral Expression requirement enhance students’ public speaking and communication skills. Courses meeting this requirement center on improving oral proficiency, dedicating over 50% of class time to the principles of effective communication.
