Answer 1

The important function of a vein in a leaf is to support the leaf blade.

Step-by-step explanation:

The important function of a vein in a leaf is to support the leaf blade. Veins in a leaf carry nutrients and water in and out of the leaf, providing support for the leaf structure. The vascular tissue in the leaf forms the veins, and the arrangement of veins is called the venation pattern.
