Question

How do plants show diversity in the type of leaf margin? Explain using 2 examples.

Answer 1

Answer:

The leaf is a flattened, lateral outgrowth of the stem in the branch, developing from a node and having a bud in its axil. It is normally green in colour and manu­factures food for the whole plant. The leaves take up water and carbon dioxide and convert them into carbohydrates in the presence of sunlight and chlorophyll. Leaves always follow an acropetal deve­lopment and are exoge­nous in origin.

Parts of leaf

• A typical leaf of Ficus religiosa (pipal) has a broad thin, flat structure called the lamina. The thin stalk below the lamina is the petiole. The lamina possesses a network of veins. The veins have both xylem and phloem elements which are continuous with similar tissues of the stem through those of the petiole.
