Monocots Vs Dicots . . Classification of Plants Plants are the fundamental building blocks of life on earth. Plants are life forms belonging to the kingdom Plantae. The scientific study has revealed at least 500,000 species of plants. The types of plants vary in size from microscopic algae, to huge sequoia trees more than 8m (26 ft) tall. Plant Kingdom is mainly classified into two . This type of plant classification is done according to how they reproduce. 1) Spore bearing plants ( Algae, mosses, ferns and their relatives) 2) Seed bearing plants. (Conifers and flowering plants) The plant kingdom can also be classified on the basis of the presence or absence of conductive (vascular) tissue. Ferns (pteridophytes), gymnosperms and angiosperms have vascular tissue which transports the nutrients and water through the plant. Mosses, liverworts, hornworts are non-vascular i.e. they do not have conductive tissue to transport sugar, water and nutrients. Flowers Monocots Dicots 3's or multiples of 4, or 5, or multiples up to 10 6, rarely more than six Embryo in seed - Cotyledons Monocots Dicots Have only one seed leaf inside the seed coat. It is often only a thin leaf, because the endosperm to feed the new plant is not inside the seed leaf. Two seed leaves inside the seed coat. They are usually rounded and fat, because they contain the endosperm to feed the embryo plant. Inside is a tiny plant called an embryo. The outer parts of the seeds are called cotyledons. They supply the food for the young plant when it's growing. Leaves Monocots Dicots The leaves are often long and narrow, with their veins in straight lines up and down the leaf. Sometimes, the veins run from the center of the leaf to the edge, parallel to one another. Leaves come in many different shapes and sizes. The veins go from the central midrib to the edge of the leaf, crossing and joining to form a netted pattern all over the leaf. Washingtonia Clivia Canna Malva Rosa Campanula Vascular Tissue - Stem Monocots Scattered vascular bundles throughout the stem. Dicots Vascular bundles only on the perimeter of the stem. Root Pattern Monocots Dicots The roots are usually The root is often a short and stringy. single long tap root with smaller roots growing from it. Fun Facts About 65,000 monocot species are known worldwide About 170,000 dicot species are known worldwide Nearly all our deciduous trees and common flowering bushes and vines are dicots, but nearly all grasses and grasslike things are monocots. Monocot or Dicot? Monocot or Dicot? The leaves appear to have parallel veins, so there's a vote for "monocot." However, this flower seems to have only two petals, and that doesn't fit either monocot or dicot. The main proof is that actually there is a third petal, a much reduced, translucent one at the flower's bottom, so there are also three petals. Therefore: Monocot.
