Question

3. In which plant organs venation is found? Describe its types
​

Answer 1

Answer:

The veins are the vascular tissue of the leaf and are located in the spongy layer of the mesophyll. The pattern of the veins is called venation. In angiosperms the venation is typically parallel in monocotyledons and forms an interconnecting network in broad-leaved plants.

Explanation:

Types of leaf venation:

The pattern in arrangement of veins in the blade of a leaf is called as venation. Two types of venation are reticulate venation and parallel venation. Reticulate venation involves net-like pattern of arrangement of veins. Most of the angiosperms with two cotyledons in the seed exhibit reticulate venation.

• In parallel - veined leaves, the veins run parallel to each other. ...

• Pinnately - veined leaves have a single primary vein or midrib, from which smaller veins branch off, like the divisions of a feather.
