Plant Sciences Major & Minor

Drive change in a field that’s changing our world

Plant Sciences is the study of plant growth, reproduction, evolution, and adaptation, as well as the use of plants for food, fiber, and ornamental purposes. 

Armed with a degree in Plant Sciences, you can make a positive difference in the world by:

  • Finding new ways to produce enough nutritious food for a growing world population.
  • Breeding plants to tolerate the heat- and drought-stress caused by climate change.
  • Developing sustainable cropping practices to produce healthful food while protecting the environment.
  • Investigating new methods to fight plant diseases.
  • Restoring damaged ecosystems to better support those who live there.
  • Conserving species, through plant collections in gardens and arboretums, for future generations.

Why study plant science at Cornell?  Here are 10 reasons.

Transfer Student Admissions

Plants form the foundation of life on the planet, providing us with oxygen to breathe, food to eat, clothes to wear, and landscapes to enjoy. But most of these things don’t happen by accident. Scientists and practitioners work hard to breed crops that are more resilient; manage pests that cause plant diseases; improve the health of soils; produce flavorful fruits, vegetables and grains; restore damaged ecosystems; and understand the underlying principles of how plants develop, grow, reproduce and evolve. After obtaining fundamental knowledge of plant science, students can concentration in topics ranging from plant systematics to greenhouse crop production; from breeding to pest management; from molecular biology to computational biology; from public garden management to organic agriculture; and almost anything in between.

Careers in Plant Sciences

People working on a large crop field.

Plant breeder

Many of our students go on to apply the tools they've learned to creation of new varieties of plants with desired characteristics. These can be as varied as disease resistance and climate resilience in our important food crops, new traits in ornamentals, or new products that meet emerging market demands. Students can go on to do this work in small seed companies, as university researchers, at large biotech firms, or as part of international organizations focused on global food security.

Arboretum director

With our concentrations in Ecology of managed landscapes and Public garden management, together with our close relationship with Cornell Botanic Gardens, students graduate with the experience and skills to manage botanic gardens, educational garden resources, and conservatories for the benefit of conservation, research, and public education.

Biotech industry scientist

Course work and student research experiences provide our students with the opportunity to learn cutting edge skills in biotechnology as well as the leadership and collaboration skills much in demand in the private sector.  While the agricultural biotech industry is a common destination for those interested in plant biotechnology, much of the skillset is readily transferable to pharmaceuticals and other biotech industries.

Grower and orchardist

Some of our students return to family  agricultural operations or are interested in becoming producers themselves. Our major provides skills and internship experiences that train students in the cutting edge skills required for successful production agriculture.

Food policy administrator

Through international internships and the coursework and faculty connections focused on international agriculture, many of our student pursue work with the federal government and international agricultural research organizations conducting both research and policy work. Some graduates also work with cities and municipalities to increase access to healthy foods.

Urban agriculture start-up

Advances in technology and interest in urban farming and indoor agriculture, together with increasing markets for fresh local produce has created a relatively new employment niche.  Some of our Plant Science Majors have coupled their plant/agriculture interests with leadership and business training to prepare for entrepreneurial ventures that address this new market.
