Malavika Jayakumar
Bsc Zoology
,• A leaf is composed of
• 1)Leaf blade:It is a flattened expanded part that contains mesophyll tiss
and vascular bundles.
• 2)Petiole:It is a stack of leaf
• Based on the differentiation of mesophyll tissuse ,leaves are divided into
• Dorsiventral leaf
• Isobilateral leaf
, • Dorsiventral leaf:
• They have anatomically different dorsal and ventral side
• Their mesophyll is differentiated into upper palisade and spongy tissues
• Mostly seen in dicots
• Isobilateral leaf:
• They have anatomically similar dorsal and ventral side
• Their mesophyll is not differentiated
• Mostly seem in monocots
