What branch of biology focuses on the study of plants?

Botany is the branch of biology that specifically focuses on the study of plants. This includes their physiological processes, structure, ecology, and evolution. Botanists investigate the various types of plants, their classifications, and their interactions with the environment, as well as how they contribute to overall ecosystems. The field of botany encompasses a wide range of topics, from plant genetics and biotechnology to the study of whole ecosystems that involve plant life.

In contrast, zoology is the study of animals, entomology focuses on insects, and biochemistry examines the chemical processes within and related to living organisms, which may touch on plant life but is not exclusive to it. Each of these other fields has its own specific focus, further highlighting why botany is uniquely dedicated to plants.
