Question

What is the petiole of a plant?

• A. The flat green part of a leaf.
• B. A stalk that attaches the leaf blade to the stem.
• C. A pigment that imparts the green colour to the leaves.
• D. The region of attachment of the leaf with the stem.

Answer 1

The correct option is B A stalk that attaches the leaf blade to the stem.

The flat green part of the leaf is known as the leaf blade or the lamina. It is attached to the stem by the means of a short stalk called the petiole. The region of attachment of the leaf with the stem is called the leaf base. The leaves contain a pigment called chlorophyll and this pigment imparts green colour to the leaf.
