Which of the following is correct about dorsiventral leaf?
1 More stomata is present on abaxial surface
2 Undifferentiated mesophyll
3 Nearly the same size of vascular bundle is present all over leaf, except main vein
4 Reticulate venation
Explanation:
The abaxial epidermis generally bears more stomata than the adaxial epidermis. The latter may even lack stomata.Mesophyll is differentiated.The size of the vascular bundles are dependent on the size of the veins. It is not of a same size all over leaf.
In grasses, certain adaxial(upper) epidermal cells along the veins modify themselves into large, empty, colourless cells. These are called bulliform cells.
