很简单，植物生物学是对植物的科学研究。植物生物学家的兴趣和专长是非常多样的，包括分子生物学和生物技术、进化与生态学、景观与生态系统生物学。由于植物是地球上几乎每一个生态系统的基础，农业进步是现代社会的基础，所以这并不奇怪植物生物学家往往很吃香。植物生物学家在外工作可以是土地管理者，研究人员，农学家和林业员，环境顾问和艺术家。在内工作，他们可以是博物馆馆长，研究人员，政府官员和老师。
Quite simply, Plant Biology is the scientific study of plants. The interests and expertise of plant biologists are quite varied, including molecular biology and biotechnology, evolution and ecology, and landscape and ecosystem biology. As plants are the foundation of nearly every ecosystem on the planet, and agricultural advancements are the basis of modern society, it is not surprising that plant biologists are often in high demand. Plant biologists may work outside as land managers, researchers, agronomists and foresters, environmental consultants, and artists. Inside, they may be museum curators, researchers, governmental officials, and teachers.
