In botany, a leaf is an above-ground plant organ specialized for photosynthesis. Muscle (organ) [**muscle is composed of many types of tissue such as muscle tissue and connective tissue, epithelial tissue, and nerve tissue so it is not a tissue, but an organ] 7. A leaf (plural leaves) is the principal lateral appendage of the vascular plant stem, usually borne above ground and specialized for photosynthesis.The leaves and stem together form the shoot. Organs are groups of tissues working for a common purpose, which is photosynthesis in the case of a leaf. For this purpose, a leaf is typically flat (laminar) and thin, to expose the cells containing chloroplast (chlorenchyma tissue) to light over a broad area, and to allow light to penetrate fully into the tissues.
