Question

After cutting cucumber if salt is added, then water comes out due to:

Answer & Solution

Answer: (Detailed Solution Below)

Option C: Osmosis

Detailed Solution:

The correct answer is “Osmosis”.
The water that comes out of a cucumber after adding salt is due to the process of osmosis.

Osmosis is a type of passive transport, which means it does not require energy input from the cell.

In this case, the salt added to the cucumber draws out water from the cucumber cells through a semipermeable membrane, which separates the inside of the cucumber from the outside environment.

The movement of water occurs from an area of low salt concentration (inside the cucumber) to an area of high salt concentration (outside the cucumber), which leads to the loss of water from the cucumber.
