(1, 2, 3) The guard cells of stomata are kidney-shaped in dicot leaf. And varies from plant to plant. A cotyledon is a seed leaf, and 'mono' means one). Monocot leaves are called isobilateral leaves since both the sides of monocot leaves are more or less similar. Monocots have one cotyledon while dicots have two cotyledons. deposition of silica. A few cells present in the upper epidermis are You May Also Like: … the mesophyll of a monocot plant leaf has no such differentiation. The shape of a dicot plant leaf is broader and relatively smaller. Ground tissue is differentiated into hypodermis, cortex, endodermis, pericycle and pith 6. The intercellular spaces are relatively large due to presence of loosely packed mesophyll cells. This group contains about 60,000 species. Log in Join now 1. Now that you know a bit more about the two main groups of flowering plants, let’s have a look at how dicots and monocots differ: Monocots: Dicots: Monocots have just one cotyledon. the leaf, a condition referred to as, The leaves of monocot plant have stomata on both surface of the leaf, In this article, learn the difference between monocot and dicot leaves. Monocotyledon seeds possess a well-developed endosperm. Isobilateral orientation is whereby plant leaf surface parts (upper and lower) In dicot leaf large vascular bundles do not show differentiation into The Italian physician and biologist Marcello Malpighi (1628 1694) was the first to use the term cotyledon (the Latin word meaning seed leaf) and John Ray (1627 1705), an English naturalist, was the first to notice that some plants have one cotyledon and others have two. monocotyledons; eudicotyledons (also called dicotyledons) Monocotyledons. Xylem is present towards the upper epidermis while the phloem towards the lower epidermis. The hypodermis is made … Flowering plants are divided into monocots (or monocotyledons) and dicots (or dicotyledons). primary vein). Monocot leaves are the leaves which appear on plants produced from seeds with single cotyledon like Maize, Rice, Orchids, Grass, Wheat, Palm trees, Bananas, magnolia tree etc. internally into mesophyll , epidermis and vascular tissues. Dicots come with two embryonic leaves. Compound Leaf: 6 Major Differences Together With Examples, 14 Difference Between Organic And Inorganic Compounds (With Examples), Understanding The Difference Between Monocot And Dicot Stem, 8 Difference Between Monocot And Dicot Seeds With Examples, 12 Difference Between Test E And Test C (Test E Vs Test C), 7 Major Differences Between Heat And Temperature, 7 Difference Between P And NP Problems In Computer Science, 5 Difference Between Primary And Secondary Seismic Waves, 6 Difference Between Polarized And Unpolarized Light, 15 Difference Between Frogs And Toads (With Similarities), 10 Difference Between DNA Polymerase 1 And 3, The guard cells of stomata are kidney-shaped in dicot leaf. The epidermis is usually made up of a single layer of cells Both monocot and dicot leaves are differentiated Depending on the number of cotyledons in the seed, angiosperms are of two types- monocot and dicot plants. Monocots: The difference between monocots and dicots can also be marked on the basis of number of pores/furrows present in a single pollen. Further, they contain a hypodermis. The vascular bundles in dicot leaf are large and generally present in the veins of the leaf. From the very beginning, a monocot is simpler. CTRL + SPACE for auto-complete. Bundle sheath extension is present in the vascular bundles of both monocot and dicot leaves. Understanding the difference between monocot leaf and dicot leaf with a diagram as well as tabular form is quite important. Dicotyledons commonly known as dicots include mango, peanut, The different tissues are arranged in concentric fashion 5. Parallel venation is whereby the secondary veins run parallel to each other off a central, perpendicular primary vein. Isobilateral orientation is whereby plant leaf surface parts (the upper and lower) are identical to each other. M.B. generally has a single layer and formed of colorless cells. Both have vascular bundles marked with sheath extension; Leaves are differentiated internally into mesophyll, vascular bundles, and epidermis; Both leaves have chloroplast; Both have stomata and guard cells; Both have vascular bundles that are differentiated ; Both have Hypodermis; Both leaves have parenchymatous. are identical to each other. Xylem is usually responsible for conduction of water In monocot and dicot leaves, xylem and phloem enlarged to form motor cells referred to as bulliform cells. Most of the plants that you see around and that which dominate the plant population belong to this group. What are the Characteristics of Monocotyledons? They both possess chloroplasts.
