OBJECTIVE FORESTRY

Detailed explanation-1: -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-2: -Petiole is the cylindrical stalk of the leaf. It raises the lamina to provide maximum exposure to sunlight for photosynthesis. It is called mesopodium.

Detailed explanation-3: -The petiole is the stalk that supports a leaf in a plant and attaches it to the stem. Many people often call it a stem, which is incorrect. A stem is the part of the plant that serves as the main source of support and produces nodes and roots, and that’s not what we observe in petioles.

Detailed explanation-4: -The petiole also called the mesopodium is a cylindrical or sub-cylindrical smooth or grooved stalk of the leaf which lifts the lamina above the level of the stem. So, the correct option is ‘Mesopodium’.
