Mesophyll (Epidermal) cells and stomata

The correct option is (B)

Explanation for correct option:

• A leaf is the part of the plant that performs the function of photosynthesis and transpiration.
• The epidermis is the outermost layer of the leaf.
• The cells found between the upper and lower layers of the epidermis in a leaf are mesophyll cells.
• One can use the leaf peel to observe stomata and epidermal mesophyll cells.

• There are two types of mesophyll cells found in a leaf: palisade and spongy.
• All mesophyll cells cannot be seen using leaf peel from the lower surface.

Option C:

• Stomata is a small opening found in leaves.
• These can be observed in leaf peels from upper and lower surfaces.

Option D:

• Guard cells are the cells that control the opening and closing of stomata.
• These are part of the stomatal apparatus and can be found in leaf peels from upper and lower surfaces.
