Question

study the given material A(Leaf of Mango) and B (leaf of Banana) and comment on their Venation with diagram​

Answer 1

Answer:

Leaf b-Banana leaves are too large in terms of size. They have been well known to comprise parallel venation. The cell of the leaf needs supply of nutrients and the venation is providing the adequate nutrients to the plant. Apart from that, the structure of the banana leaf is also maintained by the venation process

Leaf a-Mango leaf has a pinnate reticulate venation. It is characterized as a presence of a central midrib and a bunch of small veins originating from the mid rib and spread all over the leaf. This is the most common form of venation

Answer 2

Venation comes from the word veins and refers to the way in which veins are found in a leaf. In a leaf, the mid rib starts from the petiole and goes all the way to the tip of the lamina. Veins arise from the midrib.

Material A: Mango leaf: The mango leaf has reticulate venation. It is from the midrib that veins branch out in different directions.The veins further give rise to smaller veins. This type of venation is also called pinnate venation.  

Material B: Banana leaf: The banana leaf has parallel venation. The veins begin from the midrib and go towards the edge of the lamina. The veins are arranged parallel to each other. They originate directly from the midrib and not from any other veins.  

Fun fact: Plants that have leaves with parallel venation are monocot plants. Dicots have reticulate venation.
