NEET BIOLOGY

Detailed explanation-1: -Expert-Verified Answer. The part of the Human body that is most similar in function to the spongy mesophyll layer in a leaf is A) Alveoli in the lungs.

Detailed explanation-2: -In plants, it is part of the mesophyll, where it forms a layer next to the palisade cells in the leaf. The spongy mesophyll’s function is to allow for the interchange of gases (CO 2) that are needed for photosynthesis.

Detailed explanation-3: -The role of the spongy mesophyll is to facilitate the exchange of gases essential to the process of photosynthesis. Although this layer includes a few chloroplasts, it appears that its primary role is to act as a temporary storage for sugars and amino acids that are generated in the palisade layer.

Detailed explanation-4: -The cells contain lots of chloroplasts as this is the main layer for photosynthesis. Below the palisade mesophyll layer is the spongy mesophyll layer which is made up of irregularly shaped cells, which also have chloroplasts, just not as many. This is because their main role is not photosynthesis, but gaseous exchange.

Detailed explanation-5: -The most important role of the mesophyll cells is in photosynthesis. Mesophyll cells are large spaces within the leaf that allow carbon dioxide to move freely.
