Question
Distinguish between dicot and monocot leaf on the basis of following characters.
| Characters | Dicot leaf | Monocot leaf |
| Stomata | ||
| Intercellular space | ||
| Venation | ||
| Vascular bundle | ||
| Mesophyll cells |
Solution
| Characters | Dicot leaf | Monocot leaf |
| Stomata | Stomata are restricted to lower epidermis. Guard cells of stoma are kidney-shaped. | Stomata occur on both epidermis. Guard cells of stoma are dumbbell shaped. |
| Intercellular space | More intercellular spaces due to presence of spongy parenchyma | Less intercellular spaces as mesophyll is not differentiated into spongy and palisade tissue. |
| Venation | Reticulate venation | Parallel venation |
| Vascular bundle | Vascular bundles of varying size. The size of the vascular bundles is dependent on the size of the veins which vary in thickness in dicot leaf. | Vascular bundles are nearly of similar size (Except in main veins). |
| Mesophyll cells | Mesophyll tissue is differentiated into palisade parenchyma and spongy parenchyma. | Mesophyll tissue is not differentiated into palisade parenchyma and spongy parenchyma. |
