The roots help provide support by anchoring the plant and absorbing water and nutrients needed for growth. It is also used to store food. Basic parts of most all plants are roots, stems, leaves, flowers, fruits, and seeds. Dermatogen (outermost layer whose cells mature into epiblema and root cap); Periblem (inner to dermatogen whose cells mature into cortex) and. These are called aerial roots. Hence, this zone, (iii) Generally, roots grow above the ground. The enlarged cells in this region undergo differentiation to form different types of primary root tissues like cortex, endodermis, xylem, phloem, etc. Furthermore, it also expands within the ground so that for better water absorption the water increases. The primary roots and its branches constitute the taproot system. The crops that are grown on dry land have 90% of their roots in the top 10cm of the soil. The cap is multicellular and made of parenchymatous tissue. The stem carries the water to different parts of the plant. The roots hold the plant in the soil. In majority of the dicotyledonous plants, the direct elongation of the radicle leads to the formation of primary root which grows inside the soil. The root system is homogeneous and consists of the main root and its lateral branches. Zone of elongation- this region is situated just behind the meristematic region and is about 4 to 8 mm in length. In this area, the primary cells differentiate to form various cells with specific functions. 2. This system of roots provides a very strong anchorage as they are able to reach very deep into the soil. The root is commonly the underground part of the plant body that helps to anchor it down to the ground and absorbs water and minerals from the soil. Parts of the root: Primary root- originates at germination stage from the radicle of the seed. they are endogenous. branch profusely,  are shallow and spread horizontally, do not grow The roots help provide support by anchoring the plant and absorbing water and nutrients needed for growth. Adventitious roots are those which develop from any part of the plant other than radicle. Adventitious roots are those which develop from any part of the plant other than radicle. Characteristics The roots, in most plants, stay underground and are an ‘invisible’ part of the plant to most who view it. e.g. In monocots, the root cap is formed by the independent group of cells known as Calyptrogen. amazed at the abundance of root growth in their plants.  Secondary root- arise from the primary root. They do not produce dissimilar organs like leaves, buds. The roots often extend far into the ground, spreading deep and wide to ensure the plant has plenty of food and drink within its reach. They can also store sugars and carbohydrates that the plant uses to carry out other functions. The roots of most vascular plant species enter into symbiosis with certain fungi to form mycorrhizae, and a large range of other organisms including bacteria also closely associate with roots. It occupies a small fraction of the root length, and the cells here divide continuously to add new cells to the root cap and the zone of elongation. pineapple and banana flavour) and the banyan (बरगद) tree, roots arise from parts of They are an Integral or Integrated system that helps the plant in:Anchoring: Roots are the reason plants remain attached to the ground.

They are cylindrical generally non-green structures. Of course, plants don't have mouths to eat and drink, so they draw nutrients and moisture in through their r… Check the answers of worksheet on parts of a plant: Answers: I. The shoot system is heterogeneous and consists of stem, branches, leaves, and flowers. American vine having roots that hang like cords and cylindrical fruit with a Roots comprise about 1/4 to 1/3 the total weight of a plant and are essential to its growth and health.1 The functions of the roots: • Anchor the plant in the ground Plant Parts And Functions by Oon Han 1. They help to support the tree as it grows because trees can become very large and heavy.As the roots extend into the earth, they spread out and have hair-like structures on them that allow easier absorption of water and nutrients. roots in wheat (गेहूँ), maize (मक्का), sugarcane (गन्ना). In some plants, the taproot remains short but the secondary roots grow horizontally to large extend along the surface of the soil and do not penetrate deep in the soil. The roots absorb water and minerals that a plant needs to live. The parts which perform the function of sexual reproduction are called floral or reproductive parts. Roots perform various functions that are necessary for the survival of the plants. It elongates to form the primary or the taproot. the plant root system distinguished from the shoot, its functions. The primary functions of roots are: 1. roots in the mustard (Brassica) (सरसों), sunflower (Helianthus) (सूरजमुखी) plant.
