Question

Which plant shows reticulate venation?
(A) Ficus
(B) Canna
(C) Musa
(D) Zea

Answer 1

Hint:Reticulate venation is seen in Dicot plants. Veins are repeatedly branched to form a network in leaves with reticulate venation.

Complete answer:
Venation: The mode of arrangement of veins and veinlets in the leaf lamina is called venation. Venation is of two type- reticulate and parallel venation. In reticulate venation, the veins are repeatedly branched to form a network. It is a characteristic feature of dicot plants. e.g.: Hibiscus, Mango tree, etc.
In parallel venation, the veins run parallel to one another from the midrib to the margins or from the base to apex. It is a characteristic feature of monocot plants. e.g.: Grasses, banana. Etc.
In the given plants Ficus is a dicot plant and Canna, Musa, Zea are monocot plants. Therefore, plants showing reticulate venation is Ficus.

Functions of vein
Veins form the skeleton of the leaf-blade and give rigidity to the leaf. Veins help the leaf-blade to keep flat , so that it may be evenly illuminated by the sunlight.
Veins distribute water and mineral salts received from the stem throughout the leaf-blade, collect the prepared food material from the blade and send it to the stem and other parts of the plants.

Note:Branched veins and veinlet are the characteristic feature of leaf with reticulate venation. Reticulate venation is in plants belonging to Dicots. Parallel venation is seen in Monocot plants.
