Explanation:
Leaves are vital to the survival of plants. They help plants in a variety of ways, including producing 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 specialized for photosynthesis. The lamina contains the following 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.
