Leaves always follow an acropetal deve­lopment and are exoge­nous in origin. A typical leaf of Ficus religiosa (pipal) has a broad thin, flat structure called the lamina. The thin stalk below the lamina is the petiole. The lamina possesses a network of veins.

Leaves are generally composed of a few main parts: the blade and the petiole. Figure 13.1.2 13.1. 2: A leaf is usually composed of a blade and a petiole. The blade is most frequently the flat, photosynthetic part. The petiole is a stem that attaches the …

Feb 17, 2023 · Leaves are complex organs consisting of several layers serving various essential functions. They are the site of photosynthesis in plants, producing food. For cellular functions like photosynthesis and respiration, leaves require several cells and tissues to work in coordination.

What is a Leaf? The leaf is a green, flat, thin, expanded lateral appendage of the stem. This part is borne at a node and bears a bud in its axil. It is exogenous in origin and develops from the leaf primordium of shoot apex. The green colour of the leaf is due to the presence of the photosynthetic pigment – chlorophyll.
