What is leaf venation and why is it important in plants?

Leaf venation refers to the arrangement or pattern of veins present on the leaf surface. These veins form a network that helps transport water, minerals, and food materials within the leaf.

Leaf venation is important because veins provide support to the leaf structure and help substances move between different parts of the plant. The pattern of veins is also useful for identifying and classifying plants. The two common types of leaf venation are reticulate venation and parallel venation.

By observing the arrangement of veins in leaves, different plant groups can be recognised and their relationship with other features, such as root systems, can be studied.
