Structure of Root
A root is made of three regions- Meristematic region, Region of Elongation and Region of Maturation. The details are given below:
Root Cap
The root is covered at the tip by a thimble-like design. This is known as the root cap. The root cap protects the delicate root tips when it clears its path through the dirt.
Region of Meristematic Activity
This area is also known as the region of cell division. This area lies a couple of millimeters over the root cap. This is the area of meristematic action. The cells in this district are tiny and have thick cellular material. Since this is the meristematic area, the cells divide quickly.
Region of Elongation
This area lies above the region of the meristematic movement. The cells close to this region undergo through quick extension and growth. These cells help in the growth of roots.
Region of Maturation
This area lies above the region of Elongation. The root hairs are found in this region. Root hairs are essential for the root epidermis.
Root System in Plants – Types and Functions of Root
The Root System in Plants is an intricate network of structures that allows the transport of nutrients and water. A root is a piece of a vascular plant typically present under the ground. Its essential functions include ingestion of water and disintegrated minerals, conduction of these to the stem, and capacity to hold food varieties. The root is different from the stem as it lacks leaf scars and buds, has a root cap, and has branches that start from the inner tissue instead of buds.
Taproot and Fibrous Roots are the two major Types of Roots. The taproot is found deep in the soil and the fibrous root remains shallow. The roots function as an anchor and also help absorb minerals and nutrients from the soil.
