Which structure is responsible for the absorption of water in plants?
- a)Stomata
- b)Xylem
- c)Root hairs
- d)Phloem
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
Which structure is responsible for the absorption of water in plants?a...
- Root hairs are tiny, hair-like extensions of root cells.
- They significantly increase the surface area of the roots.
- This larger surface area allows for more efficient absorption of water and essential nutrients from the soil.
- While xylem transports water throughout the plant and stomata regulate gas exchange, root hairs are specifically designed for the initial uptake of water.
- Therefore, root hairs are crucial for a plant's hydration and overall health.

Understanding Water Absorption in Plants
In plants, the structure primarily responsible for the absorption of water is the root hairs.
What Are Root Hairs?
- Root hairs are tiny, hair-like extensions that grow from the root's surface.
- They significantly increase the surface area of the roots, allowing for more efficient water and nutrient absorption.
How Do Root Hairs Function?
- Root hairs penetrate the soil and come into contact with water molecules.
- They absorb water through a process called osmosis, where water moves from an area of higher concentration (the soil) to an area of lower concentration (inside the root hairs).
- This process is crucial for the plant’s hydration and nutrient uptake.
Other Structures in Water Movement
- Xylem: While root hairs absorb water, the xylem is responsible for transporting this water throughout the plant.
- Stomata: These are small openings on leaves for gas exchange and play a role in water loss, not absorption.
- Phloem: This structure is involved in the transport of nutrients and sugars, not water.
Importance of Root Hairs
- Root hairs are essential for plant health as they ensure that the plant receives adequate water, especially during dry conditions.
- They also aid in the uptake of minerals, contributing to the overall nutrition and growth of the plant.
In summary, root hairs are the key structures that absorb water in plants, making them vital for hydration and nutrient intake.
