Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is important for the uptake of water by root hair cells?
A
contractile fibres
B
large surface area
C
thick outer wall
D
vacuole
Explanation: 

Detailed explanation-1: -Water passes from the soil to the root hair cell’s cytoplasm by osmosis. This happens because the water in the soil has a higher water potential than the root hair cell cytoplasm. Root hair cells have a large surface area for absorption of water and to speed up osmosis. Was this answer helpful?

Detailed explanation-2: -Root hair cells improve plant water absorption by increasing root surface area to volume ratio which allows the root hair cell to take in more water. The large vacuole inside root hair cells makes this intake much more efficient.

Detailed explanation-3: -Q. The plants absorb water from the soil with the help of root hair through osmosis.

Detailed explanation-4: -Root hairs absorb water from the soil by the process of osmosis.

Detailed explanation-5: -Osmosis plays a central role in the movement of water between cells and various compartments within plants. In the absence of transpiration, osmotic forces dominate the movement of water into roots.
