Plants are present in a wide range around us. It is one of a large kingdom of the organism. Plants have different types of species. One of their classification is as monocot and dicots. Monocots and dicots differ from each other in four structures: leaves, stems, roots and flowers. This difference begins from the seed and remains throughout the life cycle. Monocots have one cotyledon while dicots have two cotyledons. Monocots include all grasses and grass-like plants while dicots include all our trees, bushes, etc. Monocots leaves mostly have parallel veins whereas, dicot leaves have net-veins. Dicot leaves have thick cuticle at the upper layer and thin cuticle at lower layer whereas monocot leaves have uniform cuticle on both the surfaces. Another main difference in monocot and dicot leaf is that monocot leaf has an equal number of stomata on either side, but dicot has more stomata at its lower surface.
Monocot leaves are present in monocot plants. Monocots have one cotyledon within its seed. They possess isobilateral symmetry. Monocot leaf has a double epidermal layer, one on the upper surface and other on the lower surface. The thick cuticle is present on the outer surface whereas lower surface has thin cuticle. The cells of the epidermis are filled with many chloroplasts. Bulliform cells are present on upper epidermis. Epidermis of monocots also possesses many intercellular spaces in them. Mesophyll is present in the spongy parenchyma. Monocot leaf has an equal number of stomata on either side. Monocot leaves possess parallel veins in them. Many vascular bundles are present in them. The central vascular bundle is mostly larger than others. Double layer sheath surrounds each vascular bundle. The outer layer is thick and inner layer is thin. Xylem consists of vessels and tracheids and occurs towards the upper surface. Phloem consists of tubes. Examples of monocot leaves are grass and other grasslike plants.
