Plant Biology will be one of the most active fields of science in the 21st century. Scientists have begun unlocking the secrets of the plant world and are using that information to fight hunger and disease, improve human health, develop new consumer products and pharmaceuticals, produce biofuels, reclaim damaged and disturbed landscapes, protect biodiversity and fragile ecosystems, and to conserve vital natural resources. This progress has been made possible by basic scientific research in numerous areas of plant science, including anatomy, biochemistry, cell biology, ecology, genetics, molecular biology, physiology, and systematics. While some plant biologists look below the cell level to understand the differences and similarities between plants and other organisms, others work above the cell and organism level by examining the relationships and interaction between plants and their environment. Plant biology is a diverse field of science where you can be intensely focused on a single question, or more interdisciplinary questions, crossing over into other scientific fields (microbiology, chemistry, zoology, human biology, medicine, computer science, physics, anthropology).
