In biology, morphology is the study of the size, appearances, and internal relationships of animals, plants, and microbes.
It contributes to the study of an individual's physical characteristics, such as size, form, and structure.
The roots, stems, leaves, flowers, and fruits make up a flowering plant's morphology.
Plant classification is aided by the distinguishing characteristics of stem type, leaf type, inflorescence, flower structure, fruit type, etc. that are provided by plant morphology.
Determining the evolutionary links between organisms is another benefit of studying morphology.
