Tag: Leaf structure

The relationship between a leaf and the rest of the plant is described in other topics. A typical leaf of a broad-leaved plant is needed as well as a transverse section through the leaf.) It is attached to the stem by a leaf stalk, which continues into the leaf as a midrib. Branching from the midrib is a network of veins that deliver water and salts to the leaf cells and carry away the food made by them. As well as carrying food and water, the network of veins forms a kind of skeleton that supports the softer tissues of the leaf blade. The leaf blade (or lamina) is broad.
