Question

Answer

There are two types of reticulate venation -- 1) Pinnately 2) Palmately .In palmately venation there are more number of veins which arise from the base of leaf . Hence it is also called multicostate venation .

Answer

Reticulate venation is of two types – pinnately reticulate venation and palmately reticulate venation. In palmately reticulate venation, more main veins rise from the base of the leaf. Hence, it is also called multicostate venation.

Answer

Another name for multicostate venation is palmately reticulate.

Multicostate venation refers to the arrangement of veins in a leaf or leaflet where several primary veins originate from a common point at the base of the leaf and radiate outwards in a palm-like pattern. This venation pattern can also be referred to as palmately reticulate. Let's take a closer look at this term and its meaning:

1. Multicostate venation:
- In multicostate venation, multiple primary veins arise from a single point at the base of the leaf.
- These primary veins then extend towards the leaf margins, branching further to form secondary and tertiary veins.
- The pattern resembles the palm of a hand with the primary veins resembling the fingers and the secondary and tertiary veins resembling the palm lines.

2. Palmately reticulate:
- Reticulate venation refers to a network-like pattern of veins in a leaf.
- It is characterized by the presence of multiple interconnected veins forming a net-like structure.
- Palmate means resembling the shape of a palm or hand.
- Therefore, palmately reticulate describes the multicostate venation pattern in which the veins form a network-like structure resembling the palm of a hand.

3. Comparison with other venation patterns:
- The other options given in the question, reticulate and parallel, represent different venation patterns.
- Reticulate venation refers to the presence of a network-like pattern of veins in a leaf, which can be observed in some dicotyledonous plants.
- Parallel venation, on the other hand, refers to the arrangement of veins in a leaf where the primary veins run parallel to each other from the base to the tip of the leaf, as seen in monocotyledonous plants.

Conclusion:
Multicostate venation is an alternate term for palmately reticulate venation, which describes the pattern of veins in a leaf where multiple primary veins originate from a common point at the base of the leaf and extend towards the leaf margins, resembling the palm of a hand.
