- During the evolution of multicellularity, plants adopted a division of labor whereby some organs produce energy and others consume it. The leaf is essentially a solar panel that uses photosynthetic cells to convert carbon dioxide and water into sugars and oxygen and efficiently supplies these products to heterotrophic cells.

Leaves produce food for the plant through a process called photosynthesis. The leaves of different plants vary widely in size, shape and colour and are adapted to carry out photosynthesis.
Apr 27, 2010 · A leaf develops from a few cells that grow, divide, and differentiate to form a complex organ that is precisely positioned relative to its neighbors. How cells communicate to achieve such coordinated growth and development is the focus of this review.

Oct 31, 2023 · Similar to the stem, the leaf contains vascular bundles composed of xylem and phloem. The xylem consists of tracheids and vessels, which transport water and minerals to the leaves. The phloem transports the photosynthetic products from the leaf to the other parts of the plant.

Jul 31, 2022 · Leaves are the main sites for photosynthesis: the process by which plants synthesize food. Most leaves are usually green, due to the presence of chlorophyll in the leaf cells. However, some leaves may have different colors, caused by other plant pigments that mask the green chlorophyll.
