What is the arrangement pattern of veins in leaves known as?

The arrangement pattern of veins in leaves is known as venation. It describes how veins are distributed across the leaf surface and helps in identifying different types of plants.

Veins are important structures that transport water, minerals, and prepared food within the leaf. They also provide support and maintain the shape of the leaf.

There are two main types of venation: reticulate venation and parallel venation. In reticulate venation, veins form a network-like pattern, commonly seen in plants like hibiscus and rose. In parallel venation, veins run side by side, as seen in plants like grass and maize.

The study of leaf venation helps in understanding plant diversity, classification, and the relationship between different plant features such as leaves and roots.
