How do water enter the roots from the soil?
A
diffusion
B
osmosis
C
transpiration
D
active transport
Explanation: 

Detailed explanation-1: -The root hairs take water from the soil by a process called osmosis. In osmosis, water molecules move from a region of higher concentration to a region of lower concentration through a semi-permeable membrane. The concentration of the water molecules is lower in the root hair than in the soil.

Detailed explanation-2: -Explanation: Water enters the root hairs by the process of osmosis. Osmosis is the process by which the molecules of a solvent, such as water, move from a region of its higher concentration to a region of its lower concentration through a semipermeable membrane.

Detailed explanation-3: -The process by which water enters the root hair cell is called as osmosis. Due to the semipermeability and low potential of water, water enters into root hair through osmosis.
