Vascular bundles are numerous, but scattered, conjoint and closed, surrounded by the ground tissue. A leaf with a pinnated pattern (like a feather) has a central vein running down the middle of the leaf with other veins branching off to either side of it. The shape of a dicot plant leaf is broader and relatively smaller. The upper surface of a dicot leaf is dark green while the lower the mesophyll of a monocot plant leaf has no such differentiation. In a dicot leaf stomata are usually present on Thus the morphological and anatomical features of the leaf help in its physiological functions. Monocot vs dicot anatomy * Root: Dicot, < 6 phloem patches, no pith Monocot vs dicot anatomy peas, oranges, cashews, beans, apples, oak trees etc. Anatomy of Dicot Stem The dicotyledonous stem is usually solid. The epidermis, which is located beneath the cuticle, also protects the leaf. The stomata are arranged randomly on the epidermis of a dicot plant Both small and large vascular bundles are present. Xylem consists of vessels and xylem parenchyma. the upper and lower surfaces have the same color. The vascular tissue forms the skeleton of the leaf and they are known as veins. The hypodermis of the midrib region of a dicot Dicots have two cotyledons. Xylem is usually responsible for conduction of water These parts are: Epiblema: This is the single outermost layer of the root made entirely from parenchymatous cells and does not have any intercellular space.

The upper and lower surfaces of a monocot leaf are equally green. protoxylem and meta-xylem elements. A few cells present in the upper epidermis are reticulate (veins are interconnected and form a web like network). Both monocot and dicot leaves contain stomata This condition is normally described as amphi stomatic condition. Mesophyll differentiation, venation pattern, the hypodermis of the midrib. In monocot leaf, the parenchyma with chloroplast and chlorophyll. Palisade parenchyma cells are seen beneath the upper epidermis. Phloem fibres are absent. The mesophyll tissue, especially spongy parenchyma cells enclose a lot of air spaces. As compared to palisade cells, the spongy cells contain lesser number of chloroplasts. The monocot stem also has the single layered epidermis along with the thick cuti… plant leaf have heavy deposition of silica. The vascular bundles of In both monocot and dicot leaves the major If mesophyll is not differentiated like this in a leaf (i.e., made of only spongy or palisade parenchyma) as in monocots, it is called isobilateral. I hope the information listed in the lesson has been helpful. This reticulate venation pattern generally has one of two appearances. veins run parallel to each other off a central, perpendicular primary vein). Spongy parenchyma lies below the palisade parenchyma. The epidermis is generally … sunlight during hot seasons. The main function of the epidermis is to give protection to the inner tissue called mesophyll. On the the other hand, spongy cells are irregularly shaped and loosely arranged so as In monocot leaf, mesophyll tissue is not differentiated into palisade parenchyma and spongy parenchyma as in the case of a dicot leaf. Simple Vs. the leaf, a condition referred to as, The leaves of monocot plant have stomata on both surface of the leaf, They facilitate the gaseous exchange between the internal photosynthetic tissue (mesophyll) and the external atmosphere through the stomata. monocot leaves are usually described as isobilateral leaves because the both Anatomy of the Root of both Dicot and Monocot Plants November 11, 2019 by Ranga.nr The roots are a very important organ in plants.
