The qualifications that you need to work in plant biology depends on your chosen career path. Plant biologists who work at a university or research institution need a postgraduate degree in a field such as biochemistry or genetics. Agriculture companies and commercial companies may hire research and development specialists with science skills and a bachelor’s or master’s in biology, agriculture, or plant science. Government agencies, regulatory bodies, and conservation organizations may also hire plant biologists with a postsecondary degree to perform tests, lab work, and field work on their behalf.
