What is leaves definition?

Leaves are the main photosynthetic organs of plants. They are typically flat, thin, and have a wide surface area to maximize their exposure to sunlight. Leaves are attached to the stem or branches of a plant through a petiole or a stalk, and they play a crucial role in the plant's growth, metabolism, and survival. Their primary function is to produce food for the plant through the process of photosynthesis, converting light energy, carbon dioxide, and water into glucose. In addition to photosynthesis, leaves also regulate the exchange of gases and water vapor with the environment, which is essential for maintaining the plant's hydration and releasing excess oxygen. Leaves come in a variety of shapes and sizes, and their characteristics can help identify and classify different plant species.
