Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of cells absorb water from the soil?
A
Palisade cells
B
Xylem vessels
C
Root hair cells
D
None of the above
Explanation: 

Detailed explanation-1: -Water is absorbed by the root hair cells by a process called osmosis. The concentration of the water molecules in the soil is usually higher than it is inside the root hair cells. So water is absorbed by the root hair cells from outside.

Detailed explanation-2: -Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria, which release energy from glucose during respiration in order to provide the energy needed for active transport.

Detailed explanation-3: -Plants are able to absorb water and mineral ions from the soil through the process of osmosis. Just behind the growing tips of roots are thousands of tiny root hairs. These tiny root hairs increase the surface area of the root epidermis and are the main area of osmosis.

Detailed explanation-4: -Complete answer:-Plants absorb water from the soil with the help of roots. It also absorbs minerals in organic form through root hairs. The water and minerals get transported by xylem vessels.
