Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Absorption of water in plants take place by
A
osmosis
B
diffusion
C
both (a) and (b)
D
none of the above
Explanation: 

Detailed explanation-1: -Plants absorb water from the soil by osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. The absorbed water is transported through the roots to the rest of the plant where it is used for different purposes: It is a reactant used in photosynthesis.

Detailed explanation-2: -The plants absorb water from the soil with the help of root hair through osmosis. The diffusion of water molecules through a semi-permeable membrane is called osmosis. Root hair absorbs water from soil through osmosis. Water will be absorbed by root hairs by osmosis as the environment in the soil is hypotonic.

Detailed explanation-3: -Water enters the cells of the root hair by the process of osmosis. Osmosis is the movement of water from a region of higher concentration to a region of lower concentration through a semi-permeable membrane. Hence, they perform the function of absorption.

Detailed explanation-4: -The process is known as transpiration through which water absorption in plants occurs.
