Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Plant absorbs water through the ____
A
stem
B
roots
C
leaves
D
all of the above
Explanation: 

Detailed explanation-1: -While plants can absorb water through their leaves, it is not a very efficient way for plants to take up water. If water condenses on the leaf during high humidity, such as fog, then plants can take in some of that surface water. The bulk of water uptake by most plants is via the roots.

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: -Root hairs help plants to absorb water from the soil.

Detailed explanation-4: -Absorption of water by roots takes place by two mechanism namely, active absorption and passive absorption. During active absorption, the root cells absorb water using metabolic energy released through respiration. Active absorption could be either osmotic absorption or non-osmotic absorption.
