Explain stucture of a leaf
Answers
Answer:
All leaves have the same basic structure - a midrib, an edge, veins and a petiole.
The main function of a leaf is to carry out photosynthesis, which provides the plant with the food it needs to survive.
Plants provide food for all life on the planet.
Explanation:
Leaves have several features that play an important role in photosynthesis:
A large surface area helps the leaf to absorb as much sunlight as possible.
Leaves are thin, minimising the distance for carbon dioxide to travel into leaf cells.

Plants don't survive without their leaves. They aid plants in a multitude of ways, including photosynthesis, which produces food and oxygen, as well as controlling water loss, regulating gas exchange, and transferring photosynthesis products.
The two primary components of a leaf are:
(1) Petiole- the stalk that supports and connects the leaf blade to the stem of a plant.
(2) Lamina- the photosynthesis-specialized green flat section of a leaf.
The following elements make up the lamina:
(I) Veins are the lines that run across the green flat section of a leaf, providing support and transporting both water and nourishment.
(ii) Midrib- The midrib is the leaf's center, thick, linear vein that spans the length of the leaf.
