What is Plant sciences?

Plant Sciences is the scientific study of plants. These studies are pursued in the field, in the botanic garden and in laboratories. Plants range from the largest forest trees to single-celled algae of fresh and marine waters.

The study of plants is of vital importance; they are the source of the food we eat, the oxygen we breathe, most of the medicines we use, and are core to the understanding of the processes of global climate change. Dealing with the threats from global climate change will be one of the biggest challenges of this century. Human manipulation of plants in the future will need to provide food and energy for an expanding human population, whilst conserving the biodiversity of living organisms and integrity of habitats.

Why study Plant Sciences at Trinity?

Trinity’s Plant Sciences course is unique in content in Ireland and uncommon in a European context. Uniquely, we integrate small-group teaching, field-based activities and the laboratory. Field-based teaching in ecology, physiology and plant evolution is at its heart: we consider both the whole plant and how it works in a natural context. All staff are research active with high profile, strong research interests in Ireland and the tropics. Our alumni occupy positions of note in many areas: examples include Teagasc, the OPW, Glasnevin, Kew, Edinburgh, Oman and the Missouri Botanical Gardens, Barclay Crop Protection and the UK Carbon Capture and Storage Research Centre. Consistently, our graduates have rated our course very highly indeed.

What will you study?

Trinity specialises in the study of the evolution and conservation of all forms of plant life and their response to global climate change impacts.

Courses include:

  • Plant biodiversity and conservation, Ecology, Plant physiology and global climate change, Long-term environmental change, Plant molecular biology, Pollination biology

The laboratories and greenhouses on Trinity campus, the Trinity Botanic Garden and the internationally recognised Herbarium support teaching. All courses are derived from active research lines and emphasis is placed on your own research project in the fourth year.

All students are given the opportunity to participate in field courses which take place in Ireland and the Canary Islands (Gran Canaria).


Plant Physiology; Fundamentals of Ecology; Plant Molecular Biology; Plants and the Irish Environment; Seminars, tutorials and workshops; Lower Plant Diversity and Evolution; Angiosperm Diversity and Systematics; Environmental Dynamics; Field Skills in Plant and Environmental Science (Canary Islands); Entomology; Experimental Design and Analysis; Broad Curriculum module (see


Research project; Plant Conservation and Biodiversity; Data Analysis; Global Environmental Change; Seminars, tutorials and workshops; Plant-Animal Interactions; Plant Breeding and Biotechnology; Tropical Ecology Field Trip; Environmental Impact Assessment; Estuarine Ecology.

If you would like more detailed information on all the modules offered, see:

Study abroad

Two of the field courses on offer are based abroad and there are potential opportunities available to study abroad in institutions with which we have a Memorandum of Understanding.


When you graduate you can move directly into a career related to plant biology, such as nature conservation, environmental consultancy, environmental protection, plant evolutionary biology or agricultural research as well as teaching at second-level. Alternatively, you might decide to go on to take a higher degree in Trinity or elsewhere. The skills you acquire in the third and fourth years are also widely applicable in business and industry.

Student Profile

Anne Doyle

The course is one of very few science courses where students have the opportunity to embark on inspiring field trips to Gran Canaria and Kenya. It is so varied that it covers many areas in biology including biochemistry, genetics, ecology, conservation and physiology. I accumulated a tremendous range of skills ranging from laboratory techniques, field research, reporting to knowledge of national and European Law. The important thing to remember when considering Plant Sciences is that you will graduate as a scientist and not as a gardener. I am currently working in a specialist scientific recruiting agency which is part of Cpl.
