Question

Name the plant having reticulate venation.
A) Musa
B) Mangifera
C) Oryza
D) Canna

Answer 1

The formation of vein in the leaf is called venation.It is of two types
1.Reticulate venation
2.Parallel venation

Complete answer:
Circulatory system is present in all living organisms be it humans or animals.Similarly venation in plants is equal to the circulatory system.

Venation refers to arrangement of veins in the leaves and is present in the vascular tissue of the plant.They start from the stem and run through the parts of the plant ending at the tip of the leaf.Since it starts from stems and end at the leaf they provide lots of benefits like

1. Physical support
2. Coordination
3. Transporting nutrients

Reticulate venation denotes the vein patterns found in the leaves.The veins are responsible for carrying water and food from leaves to different parts of the plant.

Plants with reticulate venation have tap roots.Reticulate venation are of two types.

1. Pinnate Reticulate venation
2. Palmate Reticulate venation

In pinnate venation only one of the midvein veins is present whereas all the other veins form a net like structure.The other name for this venation is Unicostate Venation.Example: Mangifera.

In palmate venation there are many mid veins while the other veins form a net like structure.This venation is further divided into Convergent and Divergent Venation.

Reticulate venation is defined as the irregular formation of veins which form a web network.Parallel Venation is defined as the venation in which the veins are parallely distributed.
i) Monocot plants show Parallel venation.
ii) Dicot plants show Reticulate venation.
iii) Musa and Oryza show parallel venation.
iv) Mangifera shows Reticulate venation.

Hence the correct answer is option ‘C’.

Note: The veins consist of vascular tissues that are essential for food and water transport. Leaf veins connect the blade to the petiole and lead to the stem from the petiole. In leaf veins, the two main vascular tissues are xylem, which is essential for the transport of water and soluble ions into the leaf, and phloem, which is important for the transport of carbohydrates from the leaf to the rest of the plant (made by photosynthesis).
