The middle vein of a compound leaf or a frond, when it is present, is called a rachis. Leaves have the leaflets radiating from the end of the petiole, like fingers of the palm of a hand; for example, Cannabis (hemp) and Aesculus (buckeyes). Leaves have the leaflets arranged along the main or mid-vein.

Answer 2

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
