Study Notes
Regions of the Root
- Roots are covered at the apex by a thimble-like structure called the root cap
- The root cap protects the tender apex of the root as it makes its way through the soil
- A few millimeters above the root cap is the region of meristematic activity. The cells in this region are small, thin-walled, and have dense protoplasm, which divides repeatedly
- The region of elongation is proximal to the region of maturation, extending the root in length. Cells in this area elongate and mature.
- From this region, some epidermal cells form fine, delicate, thread-like structures called root hairs.
- Root hairs absorb water and minerals from the soil.
Modifications of Roots
- Some plant roots change shape and structure to perform functions other than absorption and conduction of water and minerals.
- They are modified for support, storage of food, and respiration
- Tap roots of carrots, turnips have storage of food.
- Adventitious roots of sweet potato has storage of food.
- Banyan tree uses aerial roots for support
- Plants growing in swamps have pneumatophores (respiratory roots) growing vertically upwards to expose the roots for the absorption of oxygen from the air.
- Similar structures are found in mangrove trees.
