Question

Reticulate Venation is observed mostly in
a) Monocot plants
b) Dicot plants
c) Thallophytes
d) Bryophytes

Answer 1

Arrangement of veins as in a leaf is known as Venation .It is of three types and they are organised in network form.

Complete Answer:
Reticulate venation is one of the varieties of vein pattern classifications usually found inside leaves. It interconnects veins to form a web-like network here. It is one of the most common formations of veins in leaves, and can be found in the leaves of rose bushes, oak trees and maple trees. These veins bring water and food from the leaves all over the different parts of the plant. Particularly there are two other types of vein patterns – dichotomous and parallel. Compared to other classifications, dichotomous venation occurs very rarely and has veins that spring from each other, although, for example, venation found in Mango, hibiscusWhen all over the lamina the veins are arranged parallel to each other, this is known as parallel venation. These are found at plants in Monocot. Venation found in the grass, for example, Lilies, banana are examples of parallel venation. Thallophytes are a polyphyletic group of non-motile species which are historically called "thalloid plants," "relatively simple plants" or "lower plants." They form an abandoned division of the Plantae kingdom that includes fungi, lichens and algae, and also bryophytes, bacteria, and slime moulds.Bryophytes are low plants which are non-vascular, such as mosses, liverworts and hornworts. They play an essential role in controlling ecosystems, as they provide other plants with a significant buffer system that lives alongside and benefits from the water and nutrients that bryophytes receive.

Hence the correct answer is option ‘b’ i.e "Dicot plants".

Note: In a plant, the reticulate venation is known as when the veins of the leaf blade or lamina in the plants show the web-like or net-like pattern on both sides of the midrib.
