The function of _________ is to transport water, food and minerals in the leaf.

The network of veins in leaves is called venation. Food, minerals, and water are transported in the leaves through veins. The vasculature in the leaves helps to distribute these essential materials throughout the leaf, providing the cells with the resources they need to carry out photosynthesis and other metabolic processes. The veins also play a structural role, helping to support the leaf and maintain its shape.
