Question

Mesophyll is differentiated into palisade and spongy parenchyma is adaptation to

• A. Light intensity
• B. Reduced transpiration
• C. Low water availability
• D. Atmospheric humidity

Answer 1

The correct option is A Light intensity

Mesophyll tissue forms the bulk of the leaf. It makes up the green tissue of the leaf and consists of chloroplasts. These are mainly of two types palisade cell and spongy cell.

Palisade parenchyma is thin-walled cells with large numbers of chloroplasts. Cylindrical in shape. Responsible for photosynthesis.

Spongy mesophyll is ball-shaped cells with large intercellular spaces but contains fewer chloroplasts than palisade cells. They are differentiated in this way for the varying light intensity.

So, the correct answer is option A.
