Why do plants need roots?
A plant needs its roots in order to survive. The root system of a plant is typically found underground and has many different jobs. One of the main jobs of the root system is to anchor and support the plant in the soil.
What is the inner layer of a plant?
The vascular cylinder is the inner layer and is made up of small tubes that transport the water and nutrients both ways, up and down the plant. Roots Above the Ground. Watch your step! Aerial roots are roots that grow above the ground and across the land before they go down into the soil.
Who is the instructor for the plant roots lesson?
Instructor: Debra Patuto. Show bio. Debra has taught at elementary levels and has an M.ed with certification in elementary education and special education. Although they are mostly hidden underground, roots are an essential part of a plant. In this lesson, you'll learn all about plant roots and just what makes them so important.
Modifications of Roots
Roots may be modified to perform special functions like storage of food, support, and respiration apart from the normal functions. These modifications are found both in tap and adventitious roots.
Summary
The root is the non-green, underground part of the plant body. It develops from the radicle of the embryo. The roots are divided into taproot, fibrous root, and adventitious root. The different root regions are root cap, meristematic region, region of cell elongation, and region of maturation.
FAQs
Q.1. What are roots? Ans: The roots are the underground organ found in vascular plants that helps to absorb water and mineral nutrients from the soil.
Why is the root system important?
The root system is very important for the plant as it is branched and extended through the soil particles to fix the plant in the soil. The root system covers a large area of the soil to search for the water and the mineral salts that the plant needs, then absorbs them from the soil by the root hairs, and raises them to the other parts ...
How does the root system help plants survive?
The root system absorbs the water and the minerals from the environment, It anchors the plant in the ground, and it stores the food that has been made in the leaves by the photosynthesis process, So, the food can be used later by the plant to grow and survive.
What are the layers of the root system?
The root is subdivided and extended through the soil particles, it is composed of a number of the layers which are the epidermis layer, the cortex layer, the xylem (wood) layer and the pith layer.
What is the structure of a plant?
The plant structure. The plant consists of the root system and the shoot system, The root system consists of the roots, The shoot system consists of the leaves and the stems, The plant takes the raw materials from the environment to make its food by the photosynthesis process.
What is the role of mycorrhiza in plants?
Mycorrhiza: The roots of several plants are associated with fungi to form mycorrhiza. Mycorrhiza helps the plant in absorption of phosphorus and nitrogen from organic sources and protects the plants from attack of pathogenic fungi. 14. Growth Regulators: Roots synthesize certain growth regulations like cytokinins.
What are the free floating plants?
Free floating plants usually possess a cluster of adventitious roots from their nodes and bases to help in balancing the plants over the water surface, e.g., Lemna, Pistia, Eichhornia. 11. Photosynthesis: As in Trapa, Taeniophyllum, Tinospora, Podostemum.
How do roots help prevent soil erosion?
Prevention of Soil Erosion: Roots hold the soil particles firmly to prevent soil erosion. 5. Transport: They take part in transport of absorbed water and minerals to shoot system. Similarly, root has channels for the flow of organic food from aerial parts.

Rootless Plants: Many plants growing in aquatic habitats do not possess roots because there is little requirement for absorption of water and mineral salts , e.g., Wolffia, Utricularia, Myriophyllum, Ceratophyllum.
What is the difference between a dicot root and a monocot root?
The main difference between monocot and dicot root is that the dicot root contains xylem in the middle and phloem surrounding the xylem. Whereas in monocot root, xylem and phloem are arranged circularly.
What are fibrous roots?
Fibrous roots, on the other hand, are bushy roots in which thin, moderately branching roots grow from the stem. Rice, wheat, maize, marigold, banana and all monocotyledons are some examples of the fibrous root system.
What are the primary roots of a plant?
Primary roots are the early roots in young plants that consist of taproots, basal roots, and lateral roots. Secondary roots are the side branches of the primary roots.

Types of Roots
Regions of The Root
- A root is differentiated into four regions: 1. Root cap: 1. i. A thickened, protective cap-like structure is present at the root apex. 2. ii. The root cap cells secrete mucilage (mucus), which lubricates the passage of the root through the hard soil. 3. iii. In some aquatic plants, the root pockets are present. 2. Meristematic region: 1. i. It is situated behind the root cap. 2. ii. This region is made u…
