Question

What differentiates a dicot leaf from monocot leaf ?

Answer 1

In dicot leaf, the tissue between the upper and the lower epidermis is called the mesophyll. Mesophyll, which possesses chloroplasts and carry out photosynthesis, is made up of parenchyma.

It has two types of cells – the palisade parenchyma and the spongy parenchyma. While in monocot leaf, the stomata are present on both the surfaces of the epidermis; and the mesophyll is not differentiated into palisade and spongy parenchyma.

So, on the basis of "differentiation of palisade and spongy parenchyma" a dicot leaf can be differentiated from monocot leaf. The correct answer is "option B".
