Illustrate the sturcture of a leaf
Answers
Answer:
Each leaf typically has a leaf blade called the lamina, which is also the widest part of the leaf. Some leaves are attached to the plant stem by a petiole. ... Petioles, stipules, veins, and a midrib are all essential structures of a leaf. Within each leaf, the vascular tissue forms veins.
Leaves are called the kitchen of a tree, so leaves play very important roll to the survival of plants. They help plants to produce food and oxygen through photosynthesis, balancing water loss, regulating gas exchange, and transporting the products of photosynthesis.
A leaf has two main parts:
(1) Petiole- The stalk that supports a leaf in a plant and attaches the leaf blade to the stem.
(2) Lamina- the green flat part of a leaf that is essential for photosynthesis. The lamina contains the two parts:
(i) Veins- the lines on the green flat part in a leaf that provide support for the leaf and transport both water and food.
(ii) Midrib- The central, thick, linear vein that runs along the length of a leaf is called midrib.
