Which among the following is incorrect about importance of root system...
- Root system helps in absorption of water and minerals from soil. In plants like mangroves, breathing roots called pneumatophores are present.
- Pneumatophores grow vertically upwards and exchange gases through lenticels. Plants that grow tall derive their additional mechanical support by sending pillar like woody roots called prop roots.
Hence, the correct option is B
NCERT Reference: Topic “THE ROOT” of chapter "Morphology of Flowering Plants" of NCERT.

Which among the following is incorrect about importance of root system...
The Correct Answer is Option B: Plants that grow tall derive their additional mechanical support by sending pillar-like woody roots called stilt roots.
Explanation:
The root system plays a crucial role in the overall growth and development of a plant. It performs various functions such as anchoring the plant to the ground, absorbing water and minerals from the soil, and storing food. However, the statement in option B is incorrect because plants that grow tall do not derive additional mechanical support from stilt roots.
1. Absorption of Water and Minerals:
The primary function of the root system is to absorb water and minerals from the soil. The root hairs present on the surface of the roots increase the surface area for absorption. These hairs have a thin cell wall and are in close contact with the soil particles, allowing for efficient absorption of water and minerals through osmosis.
2. Mechanical Support:
Plants that grow tall, such as trees, derive their mechanical support primarily from the stem and branches. The stem consists of vascular tissues like xylem and phloem, which provide strength and rigidity to the plant. The stem elongates and thickens with the growth of the plant, allowing it to support the weight of leaves, flowers, and fruits.
3. Pneumatophores:
Pneumatophores are specialized roots found in certain plant species, particularly those growing in swampy or waterlogged areas. These roots grow vertically upwards from the ground and help in the exchange of gases, primarily oxygen and carbon dioxide, through specialized structures called lenticels. Pneumatophores aid in the respiration of plants by allowing oxygen to reach the underground parts, which may be submerged in water.
4. Breathing Roots in Mangroves:
Mangrove plants are adapted to saline and waterlogged environments. They possess specialized roots called breathing roots or pneumatophores that emerge from the ground and protrude above the water surface. These roots help in the exchange of gases and enable the mangroves to respire in the anaerobic conditions of the muddy soil.
In conclusion, the statement in option B is incorrect because plants that grow tall derive their additional mechanical support from the stem and branches, not from stilt roots.
