Share Your PDF File Diagram illustrating the tissue layers and their organization within monocot and dicot roots. These cells interrupt the palisade layers and are said to be the extensions of the bundle sheath. The size of the vascular bundles is reliant on the size of the veins. 3. Monocots have parallel venation in which the veins run in straight lines across the length of the leaf without converging. Dicot Root . A dicot leaf is broader in shape and relatively small. Privacy Policy3. 7. 19. Monocot roots, interestingly, have their vascular bundles arranged in a ring.

In addition, some monocots have dicot characteristics such as reticulated leaf veins. 16. A dorsiventral leaf is also called a bifacial leaf and is present mostly in Dicot plants. Each vascular bundle is surrounded by bundle sheath…………. Stomata of dicot plants are tiny pores in the lower epidermis of dicot leaves, which are surrounded by a pair of bean-shaped guards cells. Monocot and Dicot Stems: Type # 1. Share Your Word File The orientation of a dicot leaf can be described as dorsiventral. The cells of palisade region are compactly arranged and filled with chloroplasts. It is clearly differentiated into palisade and spongy parenchyma.
