A plant sciences program is an excellent choice for students who wish to learn more about the biology of plant life. Plant scientists may study trees, grasses, flowers, shrubs, and other types of plants in order to identify and analyze them.

The PhD is a doctoral degree, specifically called a "doctor of philosophy" degree. This is misleading because PhD holders are not necessarily philosophers (unless they earned their degree in philosophy!). That said, PhD recipients are able to engage in thought experiments, reason about problems, and solve problems in sophisticated ways.
