Botany

Summary

Botany, also called phytology or plant science, is the branch of natural science and biology that studies plants, especially their anatomy, taxonomy, and ecology. A botanist or plant scientist is a scientist who specialises in this field. "Plant" and "botany" may be defined more narrowly to include only land plants and their study, which is also known as phytology. Phytologists or botanists study approximately 410,000 species of land plants, including some 391,000 species of vascular plants and approximately 20,000 bryophytes.
