Where does a plant absorb the water that it uses during photosynthesis?
A
Leaves
B
Stem
C
Roots
D
Petals
Explanation: 

Detailed explanation-1: -The absorption of water in plants takes place through roots. Water is drawn up by the root hair cells through the process of osmosis. The absorbed water is passed to different parts of the plant through the roots and used to carry out distinct functions.

Detailed explanation-2: -Most of the water a plant loses is lost due to a natural process called transpiration. Plants have little pores (holes or openings) on the underside of their leaves, called stomata. Plants will absorb water through their roots and release water as vapor into the air through these stomata.

Detailed explanation-3: -Explanation: 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.
