Detailed explanation-1: -The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves the leaf stalk may be long (as in the leaves of celery and rhubarb), or short (for example basil). When completely absent, the blade attaches directly to the stem and is said to be sessile.

Detailed explanation-2: -The petiole is a stalk that connects the blade with the leaf base. The blade is the major photosynthetic surface of the plant and appears green and flattened in a plane perpendicular to the stem.

Detailed explanation-3: -The leaves of a plant are made ot the blade and the petiole. The blade is usually the largest part of the leaf. The petiole is a stalk that supports the leaf blade.

Detailed explanation-4: -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.

Detailed explanation-5: -The stalk of the leaf is called petiole. The stalk bearing flowers is called peduncle. The stalk of a single flower is called a pedicel. Stipules are small lateral outgrowths on either side of the leaf base.
