Question

Draw and label the parts of regions of root.

Accepted Answer

Roots are a part of the plant which is responsible for anchoring the plant body to the ground and to absorb water and minerals for the plant. There are four regions of root as described below:

Root cap region: The tip of the root is covered with a root cap, which secretes mucilage so that the root can make its way deep into the soil. This region gets degraded and renewed constantly.

Meristematic region: The cells of this region are thin-walled and filled with dense protoplasm. The cells of this region divide actively.

Region of elongation: The cells of this region elongate so that the root can grow along its length. This region contains the newly formed cells, which have lost the power of division, and then they elongate rapidly.

Region of maturation: The cells in this region differentiate to form tissues. Unicellular extensions called root hair arise from this region, which help in the absorption of water and nutrients from the soil. This region is also responsible for the production of lateral roots.

The diagram shown below describes the regions of the roots.
