NEET BIOLOGY

Detailed explanation-1: -Spongy mesophyll tissue is packed loosely for efficient gas exchange. The spongy mesophyll cells are covered by a thin layer of water. Gases dissolve in this water as they move into and out of the cells.

Detailed explanation-2: -The spongy mesophyll is a complex, porous tissue found in plant leaves that enables carbon capture and provides mechanical stability.

Detailed explanation-3: -Spongy mesophyll-loosely packed cells with large air spaces between them. The air spaces allow movement and exchange of gases, specifically oxygen, carbon dioxide, and water vapor.

Detailed explanation-4: -Many plant leaves have two layers of photosynthetic tissue: the palisade and spongy mesophyll. Whereas palisade mesophyll consists of tightly packed columnar cells, the structure of spongy mesophyll is not well characterized and often treated as a random assemblage of irregularly shaped cells.

Detailed explanation-5: -Stomata and Gas Exchange Stomata or pores in the leaf surface are surrounded by specialized leaf cells called guard cells (see Figure 3). Guard cells regulate the opening and closing of stomata. Stomata allow oxygen and carbon dioxide to either enter or leave the plant.
