Parts and their functions

• Lamina (leaf blade) (पर्णफलक) — Green expanded part with veins and veinlets — main site of photosynthesis.
• Midrib (मध्यशिरा) — Middle prominent vein.
• Veins (शिराएँ) — Give rigidity and carry water, minerals and food. Network = reticulate (dicots); parallel = monocots.
• Petiole (पर्णवृंत) — Holds the blade to light; long flexible petioles let it flutter, cooling the leaf.
• Leaf base (पर्णाधार) — Attaches the leaf to the stem; a sheath in monocots, swollen pulvinus in some legumes.
• Stipules (अनुपर्ण) — Two small leaf-like structures at the leaf base.
• Axillary bud (कक्षस्थ कलिका) — Bud in the axil of the leaf; develops into a branch.
