Question

define parallel venation and reticulate venation

Answer 1

Reticulate venation is in which the veins and the  vein lets are distributed forming a network. dicotyledons  like mango ,peepal show this type of venation.it is important to note that plants with tap root will have this type of venation.

when the veins run parallel to each other from the base to the tip of the lamino, it is called as parallel venation.it can be easily observed in leaves like rose plant, banana, wheat palms etc.,  plants with fibrous roots will  always have leaves with parallel venation.

Answer 2

The arrangement of veins and veinlets in the lamina is known as venation. The viens are in fact conducting strands of lamina. They are concerned with the conduction of water, mineral salts and food and form the structural framework of the lamina. The venation is mainly of two types.

1) Reticulate venation:
when the veins and veinlets form a network, it is called reticulate venation. Here the midrib is centrally placed and veins and veinlets remain distributed laterally. It is found in dicotyledonous plants.

2) Parallel venation:
In this type of venation, veins in lamina run almost parallel to one another .
example:
maize
glasses.
