Question

Define leaf and it's structure​

Answer 1

Answer:

Typically, a leaf consists of a broad expanded blade (the lamina), attached to the plant stem by a stalklike petiole. In angiosperms leaves commonly have a pair of structures known as stipules, which are located on each side of the leaf base and may resemble scales, spines, glands, or leaflike structures.

Answer 2

A leaf is referred to as the plant's "kitchen.". This is due to the fact that they are the primary organ responsible for photosynthesis, which is how the plant generates energy, or food. The presence of chlorophyll is what gives them their green hue. Let's get to know them better.

Two main parts of plant

• The lamina is another term for the leaf blade. It's broad and flat in general. Photosynthetic activity happens in this stratum. It has a pronounced midrib, which is the major vein, running across the centre of the leaf blade. Veins branch out from the midrib. Depending on the type of edges, vein pattern, and number of blades per leaf, they come in a variety of shapes and sizes.

• The petiole is a stalk-like structure that links the leaf blade to the stem of the plant. The veins on the leaf blade and the stem are connected by small tubes in the petiole. A few of them allow water to reach the leaf, while others move food away from it to other parts of the plant.
