As we all know that living things right from the tiny cyanobacteria to the giant blue whales, every living thing needs water to survive. Without water, life as we know it, would not exist. But have you ever given much thought to “How plants absorb water ?” Plants can absorb water through their entire surface – roots, stems, and leaves. But the root is the main organ for water absorption. Beside these roots also anchor the plant body to the ground and get modified into various forms for different functions. In this video, we will learn about the various modifications of the root Modifications for support Function of Roots in Plants : Roots are modified into two different forms to give extra support to the plant. (1)Prop The hanging roots of banyan trees are called prop roots which provide mechanical support to the tree. Example - Ficus benghalensis. (2) Stilt roots The supporting roots of sugarcane coming out of lower nodes of the stem are called stilt roots. Example - Saccharum officinarum. Modification for respiration In plants growing in swampy areas, the roots grow vertically upward, such roots are called pneumatophores which help to get oxygen. Example - Avicennia germinaus. Modifications for food storage Taproots of carrot, turnips and adventitious roots of sweet potato, get swollen and store food. There are some examples of different modifications for food storage. Moniliform: Adventitious roots are swollen at frequent intervals. This gives the root a beaded appearance. Example - Sweet potato (Ipomoea batatas) Conical: In the conical form of root modification the roots are swollen and are broad at the base, the apex part gradually tapers forming a cone-like structure. Example - Carrot (Daucus carrots) Fusiform: is a modified taproot. The primary root of the system is swollen at the middle and tapers gradually at both ends forming a spindle-shaped structure. Example - Radish (Raphanus sativus) Napiform: The napiform roots are spherical in shape at the upper part and are sharply tapering towards the tip of the root. Example - Beetroot (Beta vulgaris) Fasculated: These are tuberous roots arising in the cluster from the base of the stem. Example - Asparagus Officinalis. Nodulated: The roots having the irregular or the round mass or a lump called nodules within the cells are known as nodulated roots. Example - Pea (Pisum sativum) Thanks for watching Download Extraclass.com app: - Play Store: http://bit.ly/extraclassapp Follow us on our social media handles to stay updated.
