Why is this course for me?

Plant Biology is the scientific study of plants, fungi and algae. Plants are vital for supporting and maintaining the atmospheric and environmental conditions required for all life on Earth. They are the mainstay of human and animal diets, while also providing pharmaceuticals, timber, paper and clothing.

Plants are being exploited as sources of renewable energy and biofuels, and make an important contribution to measures aimed at reducing the effects of climate change. A key to the further development of plants for practical or economic use is an improved understanding of metabolic and developmental processes and their interactions with environmental factors.

Career & Graduate Study Opportunities

Plant Biology graduates have obtained positions as:

  • Plant and environmental scientists
  • Pollution biologists
  • Molecular geneticists and cell biologists
  • Agronomists, horticulturalists, foresters, park rangers
  • Environmental consultants
  • Wildlife, conservation, biodiversity or heritage officers

Graduates are also eligible to pursue MSc programmes in UCD in World Heritage Management and Plant Biology and Biotechnology, in addition to PhD programmes both in Ireland and abroad.

What Will I Study

This is a sample pathway for a degree in Plant Biology. Topics include plant biotechnology, applied plant biology, marine botany, genetics and systems ecology.

First Year

  • Biology
  • Chemistry
  • Mathematics
  • Optional Science modules
  • Elective modules

Second Year

  • Plant Biology
  • + 2 Other Science Subjects
  • Elective modules

Third Year

  • Plant Biology
  • Elective modules

Fourth Year

  • Plant Biology (includes a research project.)

All Science courses are full time, with many student timetables running from 9.00am to 5.00pm or later. Depending on the subject choices, a weekly timetable can include lectures, practicals and tutorials.

Assessment varies with each module but may comprise continuous assessment of practicals, written exams and online learning activities.

“I always planned on studying Science but wasn’t sure which area. This made Science in UCD the ideal choice. For the first two years, I tried modules from all the disciplines in Science which left me more informed to pick the subject I would major in. Plant Biotechnology and Plant Pathology particularly interested me, so I chose Plant Biology. I’m in third year and I’m really enjoying it. Our classes are specific to Plant Biology, the class sizes are smaller and we have lots of contact with lecturers and tutors. UCD’s vast range of clubs and excellent facilities was another major attraction for me as I’m a big fan of GAA and love playing camogie. I’ve been involved with the club every year and have had the best times playing here.”
