A leaf consists of several key parts, including:

Blade or lamina: This is the flat, green, and expanded portion of the leaf that performs photosynthesis.

Petiole: This is the stalk-like structure that attaches the blade to the stem.

Midrib: This is the central vein that runs the length of the blade and provides support.

Veins: The veins are the network of smaller veins that branch out from the midrib and provide additional support and transport water and nutrients to and from the blade.
