The study of the physical structure and function of plants is known as botany. It encompasses various aspects, including the classification, physiology, and ecology of plants. Botany examines how plants develop, grow, and adapt to their environments. This field is critical for understanding plant diversity and the roles that plants play in ecosystems, including their contributions to oxygen production and as a source of food for humans and animals. It also has practical applications in agriculture, horticulture, and conservation.
