Plants are fundamental to all aspects of our existence; they provide the oxygen we breathe and contribute to our nutrition, the clothes we wear, the infrastructure we inhabit, and the natural beauty that surrounds us.  Given the growth of the human population and the effects of this growth on the environment, research and training in the Plant Sciences has never been more critical.  After solid training in fundamental sciences, Plant Science majors customize their education with diverse and interdisciplinary electives in fields such as genetics, genomics, development, biotechnology, plant pathology, environmental horticulture, and sustainable agriculture.  Coursework and optional research training prepare majors for post-graduate studies in research, medicine, and pharmacy, or careers in horticulture, agriculture, microbiology, or biotechnology.

Transfer students are strongly encouraged to use this site for reference only and not for self-advising.

Transfer students should work with their community colleges and UA advisors to develop an individualized plan for transfer, and visit

  • All posted Pathways (except for Bachelor of Applied Science Pathways) fulfill an AGEC and most also fulfill an Associate Degree
  • Following a Pathway does not guarantee admission to the UA nor admission to a college/major/program at the UA
  • Use Pathways in consultation with advisors from your community college and the UA
  • Pathways are subject to change at any time
