What term is used to describe the study of plant life?

The term used to describe the study of plant life is botany. It is a branch of biology that examines plants, including their structure, growth, reproduction, classification, physiology, ecology, diseases, and evolutionary relationships.

The word comes from the Ancient Greek botanē, meaning “pasture,” “herbs,” or “fodder.” Botany began with practical herbalism, as people identified plants that were edible, poisonous, or useful as medicines. Ancient Greek philosopher Theophrastus, a student of Aristotle, is widely regarded as the father of botany because of his systematic work describing plants.

Botany is broader than simply identifying flowers and trees. Modern botanists may study plant cells and genes, plant communities, crop improvement, forests, fossils, or the ways plants influence global carbon and water cycles. Related specialties include plant anatomy, plant physiology, plant ecology, taxonomy, and plant pathology.

The other options describe different fields: mycology studies fungi, ornithology studies birds, and zoology studies animals. Algae may be studied in phycology, while dendrology focuses specifically on woody plants and trees.
