Difference between monocotyledons leaf and dicotyledons leaf.

Answer» The main characteristic feature that differentiates a\xa0monocot\xa0and a\xa0dicot leaf is\xa0that, the guard cells\xa0of\xa0stomata are kidney-shaped in\xa0dicot leaf\xa0and dumb-bell shaped\xa0in a monocot leaf. ... The vascular bundle\xa0is\xa0large in\xa0dicot leaf\xa0whereas in\xa0monocot leaf, both small and large vascular bundles are present.\t\xa0
Difference Between Dicot Leaf and Monocot Leaf
\xa0
Dicot Leaves
\xa0\xa0
Monocot Leaves
\xa0\xa0
Shape
\xa0Dicot plants have leaves that are relatively smaller and broader than monocot plantsMonocot plants have leaves that are characteristically longer and slender\xa0
Stomata
\xa0Stomata in dicot leaves are kidney-shapedStomata in monocot leaves are dumb-bell shaped\xa0
Arrangement of Stomata
\xa0Dicot leaves are hypostomatic – which means stomata are present on the lower surface of the leafMonocot leaves are amphistomatic – which means the stomata are present on lower as well as the upper surface\xa0
Nature of Orientation
\xa0Dorsoventral orientationIsobilateral orientation\xa0
Leaf Surface Characteristics
\xa0Dicots leaves have a dark green upper surface and a light green lower surfaceNo such differentiation. Both sides have the same colour.\xa0
Size of Vascular Bundles
\xa0LargeSmall as well as large vascular bundles are present\xa0
Intercellular Space
\xa0Due to the presence of mesophyll cells, dicot leaves have large intercellular spacesMonocot leaves have comparatively tighter intracellular space due to the compact arrangement of mesophyll cells\xa0
Differentiation of Mesophyll
\xa0Differentiated into two parts – upper palisade and lower spongy mesophyllNo such differentiation in a monocot leaf\xa0
Venation Pattern
\xa0Reticulate venation (web-like pattern)Parallel venation (Veins do not join other veins)\xa0
Characteristic of the Hypodermis of the Midrib
\xa0CollenchymatousSclerenchymatous\xa0
Bundle Sheath Extension
\xa0ParenchymatousSclerenchymatous\t
