What is mesophyll in plants?

• A. Outer layer of the leaf
• B. Green tissue in the interior of the leaf
• C. Root tissue
• D. Stomatal openings

Answer: (B)

Mesophyll refers to the green tissue found in the interior of the leaf, primarily responsible for photosynthesis. This tissue is located between the upper epidermis and the lower epidermis of the leaf and comprises two main types of cells: palisade mesophyll and spongy mesophyll. The palisade mesophyll contains tightly packed cells that contain a high concentration of chloroplasts, making it particularly effective in capturing sunlight for photosynthesis. The spongy mesophyll, on the other hand, has more air spaces that facilitate the exchange of gases, such as carbon dioxide and oxygen, which are essential for the photosynthetic process. This structure allows for efficient light absorption, gas exchange, and support for the leaf's overall function in plant metabolism.
