The arrangement of veins in leaves is called venation, and it differs clearly between monocots and dicots.
- In monocots:
The veins are parallel to each other. This is called parallel venation.
Example – grasses, maize, wheat, banana. - In dicots:
The veins form a branched or network-like pattern. This is called reticulate venation.
Example – mango, hibiscus, pea.
Summary:
- Monocots → Parallel venation
- Dicots → Reticulate (net-like) venation
