Question

Water is absorbed by the root hair cells through

• A. osmosis
• B. active transport
• C. diffusion
• D. blending

Answer 1

The correct option is A

osmosis

The correct option is A.

Explanation of the correct option:

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

Explanation of the incorrect options:

Option B :

Active transport is the movement of the molecules or ions of a substance from a region of their lower concentration to a region of their higher concentration region using energy.

Option C:

Transpiration is the evaporation of water from plants through the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis..

Final answer: Water is absorbed by the root hair cells through osmosis.
