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.
Leaves are covered with a thin layer of epidermal cells which permit light to the interior of the leaf, yet protect the cells from physical damage. In addition to photosynthesis, leaves are involved in other vital plant functions. Respiration is a metabolic process that produces waste products.
Leaves are the primary sites of photosynthesis and manufacture food for plants. They are an integral part of the stem system and can be modified into a variety of other plant organs.
Perennial plants whose leaves are shed annually are said to have deciduous leaves, while leaves that remain through winter are evergreens. Leaves attached to stems by stalks (known as petioles) are called petiolate, and if attached directly to the stem with no petiole they are called sessile.
Aside from adding beauty to trees, leaves are essential to life cycle of any plant. Here's everything you need to know about the different types of leaves.

Leaves and different parts of leaves can have various shapes and sizes. The basic components of leaves in flowering plants (angiosperms) include the blade, the petiole, and the stipules.
Leaves are shoot structures that attach to stems and branches at nodes. Leaves are made up of cells that usually contain a high concentration of chloroplasts (cell organelles unique to plants) and are specialized sites for photosynthesis.
