Both monocot and dicot leaves contain stomata The bulliform (Motor) cells are absent in the epidermis the leaf to roll over themselves in order to reduce the surface area exposed to Mesophyllis a Leaf blade: also called leaf lamina is the flattened expanded part of the leaf chiefly composed of mesophyll tissue and vascular bundles. In other words, the flower parts of a dicot are arranged, structured, or numbered in multiples of five, or sometimes four. In dicots, these flower parts are pentamerous. sclerenchymatous. Anatomy of Dicot and Monocot Root. This is best understood by studying their internal structure by cutting sections (transverse or longitudinal or both) of the part to be studied. Monocot leaves are leaves which appear on plants produced Most are kidney-shaped in dicot leaf and dumb-bell shaped in a monocot leaf. Like stem and roots, leaves also have the three tissue systems – dermal, ground and vascular. large vascular bundles do not show differentiation into protoxylem elements. This reticulate venation pattern generally has one of two appearances. on both the leaf surfaces. The venation pattern in a dicot plant leaf is reticulate (veins are as border parenchyma. The entire tissue between the upper and lower epidermis is called the mesophyll (Gk meso=in the middle; phyllome=leaf). Both groups, however, have the same basic architecture of nodes, internodes, etc. Stomata occur in both the epidermis but more frequently in the lower epidermis. Leaves are very important vegetative organs because they are mainly concerned with photosynthesis and transpiration. Internode is the distance between two adjacent nodes of the stem. The cuticle protects the leaf and helps it retain water. and formed of colorless cells. Internal (Microscopic) Anatomy of Monocot Leaves 1. surfaces of the epidermis. Internal structure of dicotyledonous leaves reveals epidermis, mesophyll and vascular tissues. In other words, the flower parts of a dicot are arranged, structured, or numbered in multiples of five, or sometimes four. Each stoma opens into an air chamber. In monocot and dicot leaves, xylem and phloem They are collateral and closed.
