Draw the Diagram of leaf and explain the parts of leaf.
Answers
Explanation:
Leaves have two main parts: The leaf blade and the Stalk or the petiole.
The leaf blade: It is also called the lamina. It’s generally broad and flat. It is in this layer that photosynthesis occurs. It contains a prominent midrib at the center of the leaf blade which is the main vein. From this midrib arise branches called veins. They are of different types depending upon the type of edges, the pattern of the veins and the number of blades per leaf.
The petiole: It is the stalk-like structure which connects the leaf blade to the stem. The petiole has tiny tubes, that connect the veins on the leaf blade to the stem. Few of these enable water transport to the leaf while the other carry food away from the leaf to other parts of the plant.
Some plants also contain another part called stipules. These are small flap-like structures that grow at the base of the petioles. They are protective in some plants when they protect the growing petiole while in others, they fall off once the petiole starts growing.
Answer:
Each leaf typically has a leaf blade ( lamina ), stipules, a midrib, and a
margin. Some leaves have a petiole, which attaches the leaf to the stem; leaves that do not have
petioles are directly attached to the plant stem and are called sessile leaves.
