Detailed Solution

The veins and veinlets of leaves always give rigidity to the leaf blade. The pattern of veins on leaf is called venation, which is of two types- reticulate or parallel. The plants with reticulate venation have tap roots and plants with parallel venation have fibrous root. Axillary buds are always present in the axil of the leaf. The axil of the leaf is present between the petiole and the stem.
