Plant morphology refers to the study of the physical characteristics and structures of plants. There are several synonyms for this term such as plant anatomy, botany, phytology, dendrology, and plant sciences. Plant anatomy specifically refers to the internal structures of plants such as cells, tissues, and organs. Botany and phytology are broader terms than plant morphology, encompassing the study of all aspects of plants including their classification, growth, evolution, and ecology. Dendrology focuses on the study of trees and woody plants, while plant sciences is an umbrella term that includes all aspects of plant research.
