Sometimes the root changes their shape and gets modified to store reserve food as found in sweet potato, radish, and carrot plant. They are also modified for respiration (e.g., roots of mangrove tree), and additional support (e.g., aerial roots of banyan tree).
Origin and Development
What Are the Main Parts of a Plant Root System
1) The Region of Root Cap
2) The Region of Cell Division (Meristematic Region)
3) The Region of Elongation
4) The Region of Maturation or Differentiation
Functions
Carrying water and minerals from the soil Protecting the sensitive growing tissues in the root Secreting the viscous mucilage that helps the root to penetrate the soil Communicating with soil microorganisms
The root cap is absent in some aquatic and parasitic plants, where they are replaced by a more specialized structure called root pocket. They do not have the protective functions of a root cap and also the capability to divide. Functions
Performing cell division to produce new cells for the developing root Helping in root elongation
Functions
Helping to increase the length and size of the root cell that has lost the ability to multiply. Helping in the absorption of water and minerals from the soil
Functions
Keeping plants and trees attached to the soil Forming specialized tissues like root hairs, xylem, and phloem that helps in absorption and conduction of water and minerals from the soil
