Answer 2

Answer:

RETICULATE VENATION :

• Reticulate venation is a type of arrangement of veins, forming a network.
• It is a characteristic feature of the dicot leaf.
• In reticulate venation, a central vein (called the midvein or midrib) occurs in the middle of the leaf.
• The branches of the midvein give rise to the secondary veins, which extend towards the margin of the leaf.
• Some of these secondary veins form a particular construction called hydathodes at their terminations.
• Hydathodes are specialized secretary organs, which are involved in guttation. 

Pinnate reticulate venation –

All the veins, apart from the midvein, are involved in the formation of the network in reticular venation. 

Palmate reticulate venation –

Many midribs occur in palmate reticulate venation while the rest of the veins form the reticular network.

PARALLEL VENATION :

• Parallel venation is a type of arrangement of veins in which the veins occur parallel to each other.
• It mainly occurs in monocot leaves.
• The two main types of parallel venation are pinnate parallel venation and palmate parallel venation.

Pinnate parallel venation –

The parallel veins arise from a prominent midvein present in the center of the lamina of the leaf in a perpendicular manner from the base to the apex.

PALMATE PARALLEL VENATION

Many parallel veins are present in the palmate parallel venation, which are prominent.
