The roots, in most plants, stay underground and are an ‘invisible’ part of the plant to most who view it. Root cap– also called calyptra, its a cap-like protective covering over the tip of the root.

Root modifications are changes in form, structure and physiology of roots to perform functions other than absorption and conduction of water and minerals. A broken or injured root cap is replaced. Roots are the most overlooked parts of plants, because in nature, we do not see them as we do the stems, leaves, and flowers. They absorb water and minerals from the soil, synthesise plant growth regulators, and store reserve food material. By undergoing modifications in their structure, roots perform special physiological functions like food storage, assimilation, absorption of atmospheric moisture, sucking food from the host, better gaseous exchange and mechanical functions like floating (buoyancy), stronger anchorage and climbing. In some plants, like grass (घास), Monstera (a tropical Absorption of water and nutrients from the soil They help plants to absorb water and nutrients from the soil, which are essential for their survival. the elongation zone gradually differentiate and mature. Hence they act as a deep feeder. Root hairs are not permanent, and they shrivel up after some time. Learn more about the types of roots, their functions, how they grow, and their morphology. Characteristics The primary functions of roots are: 1. An ecological study of adaptation by the organism to the environment is studied using morphology. Roots often function in storage of food and nutrients. roots in wheat (गेहूँ), maize (मक्का), sugarcane (गन्ना). A few millimetres above the root cap is the region of meristematic activity. By knowing them, you also know how to deal with any nasty infections that may take their toll on the dental pulp. It forms the basis for breeding experiments. The Five Parts of Roots are. This region is called the piliferous region. Roots grow underground. The roots help provide support by anchoring the plant and absorbing water and nutrients needed for growth. The permanent region (zone of differentiated cells) lies behind the root hair zone and is without hairs. e.g. In this area, the primary cells differentiate to form various cells with specific functions. The root system is homogeneous and consists of the main root and its lateral branches. The cells present here are meristematic in nature and are thus small, thin-walled with dense protoplasm. Roots also play the role of anchors which helps in creating better stability. They support the plant body, ensuring that it stands erect.Absorption: Primary function of roots is to absorb water and dissolved minerals from the soil. It gives information about the range of variations found in a species. organisms and their specific structural features. Check the answers of worksheet on parts of a plant: Answers: I. A cluster of slender, fibre-like roots arises from the 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. the plant other than the radicle and are called adventitious roots. It gives off lateral branches (secondary and tertiary roots) and thus forms the taproot system. Root. All lateral branches are produced in acropetal succession, i.e. Parts of a Root and Their Functions. Root, in botany, the part of a vascular plant that is normally underground. This area continuously receives new cells from the meristematic part. monocotyledonous plants, the primary root is short-lived and is replaced by a 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. region of elongation. The outer cells of the cap get sloughed off due to friction, and these cells are replaced by new cells from a growing part. roots. The primary roots and its branches constitute the taproot system. branch profusely,  are shallow and spread horizontally, do not grow This part of the plant is mainly responsible for anchoring it down into the ground and absorbing the essential mineral elements, nutrients, and water from the soil. The cells of this region are very small, thin-walled and with a dense protoplasm and divide actively. A part of speech is a term used in traditional grammar for one of the nine main categories into which words are classified according to their functions in sentences, such as nouns or verbs.Also known as word classes, these are the building blocks of grammar. The enlarged cells in this region undergo differentiation to form different types of primary root tissues like cortex, endodermis, xylem, phloem, etc. Discuss the roles of each part of a plant, and challenge your student to re-label the plant. The primary root is short-lived and in plant’s life, it is replaced by adventitious roots. Root doesn’t have nodal divisions; however, it is divided into five main areas on the basis of the growing stage of cells present in that area. The crops that are grown on dry land have 90% of their roots in the top 10cm of the soil. It gives off lateral branches (secondary and tertiary roots) and thus forms the root-system. The two kinds of roots tap roots and fibrous roots. The roots anchor the plant to the ground and support the above ground part of the plant. The three types of root systems also show modifications. From this region some of the epidermal cells form very fine and delicate, thread-like structures called root hairs. Each of the lessons in this program is interdisciplinary, designed to introduce students to plant science and increase their understanding of how food grows. The surface in this zone has thick-walled impermeable cells through which there is no absorption of water or minerals. Root. Root doesn’t have nodal divisions; however, it is divided into five main areas on the basis of the growing stage of cells present in that area. Just like you, plants need to take in water and nutrients to stay alive. They do not The cells of root cap secret mucilage which lubricates the passage of the root through soil. The roots of a tree are the contact point between the soil and the tree. The root system is homogeneous and consists of the main root and its lateral branches. proximal to the region of elongation, is called the region of maturation. Root hairs are short-lived and are replaced every 10 to 15 days. This system of roots provides a very strong anchorage as they are able to reach very deep into the soil. They are the major part that anchors the plant firmly in the soil. At places, endogenous growth produces lateral roots. Some plants, such as grasses, have shallow fibrous roots that appear similar to tiny hair-like fibers. Parts of a Root 18.
