Detailed explanation-1: -Function of Lamina of a Leaf It plays a crucial role in gas exchange, allowing for the absorption of carbon dioxide and the release of oxygen during photosynthesis. The lamina is also responsible for transpiration, which is the process of water loss from the leaf through tiny pores called stomata.

Detailed explanation-2: -Leaves are adapted for photosynthesis and gaseous exchange. They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out.

Detailed explanation-3: -The palisade mesophyll layer is where most of the photosynthesis occurs in the leaf. The palisade cells contain a lot of chloroplasts to help them perform this photosynthesis. The palisade cells are closely packed together to maximize light absorption.

Detailed explanation-4: -Leaf function The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.
