Part of the leaf which allows the diffusion of gases to occur
|
|
Palisade Cells
|
|
|
Spongy Mesophyll Cells
|
|
|
Epidermis
|
|
|
Phloem

Explanation:
Detailed explanation-1: -The only way for gases to diffuse in and out of the leaf is though small openings on the underside of the leaf, the stomata. These stomata can open and close according to the plant’s needs. The tissues of the leaf in between the epidermal cells, into which gases diffuse from the stomata, are called mesophyll.
Detailed explanation-2: -Here they dissolve in the water layer and diffuse into the mesophyll cells through the cell wall and cell membrane. There are holes found in leaves called stoma. These holes allows gases to diffuse in and out of the leaves.
Detailed explanation-3: -The mesophyll has two layers: an upper palisade layer and a lower spongy layer. Stomata on the leaf underside allow gas exchange.
