Question

Venation is generally reticulate in
A. Monocot plants
B. Bryophytes
C. Thallophytes
D. Dicot plants

Answer 1

Venation is the arrangement of the veins on the lamina of the leaf, and the process of arrangement is called venation in plants and there are two types, which include Reticulate and Parallel Venation.

Complete answer:
Veins are composed of both the Xylem and Phloem cells embedded in the Parenchyma, and sometimes the sclerenchyma, and these all are surrounded by the bundle sheath cells.
The xylem cells in the veins of the leaves are generally transported water from the petiole throughout the leaf lamina mesophyll, and at the same time, the phloem cells transport the food synthesized by the plants during photosynthesis are taken from the leaves to the rest of the plant.
Types of venation.
Reticulate venation: This is the type of venation, where there is an irregular arrangement of veins that are seen and where they form the network.
This Reticulate Venation is commonly seen in the dicot plants, some of the examples include, hibiscus, papaya, coriander, and Mangifera.
Parallel Venation: This is the type of venation where there is a parallel arrangement of veins on the leaves.
Examples of the parallel venation are grains, Oryza, banana, and maize.

So from the above explanation, the correct option is D.

Note: Angiosperms have the greatest amount of diversity in the case of the vein structure. Where the Lower veins are arranged typically in the three orders, which are first-order veins that are formed from the petiole and extended to the tip of the leaf lamina and the second-order veins are generally shows the branching from the first order veins, while third-order veins in turn from the small branchings from the second-order veins.
