The movement of water molecule from a region of higher concentration to a region of its lower concentration through a semi permeable membrane is called Osmosis.
a) In the above statement, how will you differentiate active transport from passive transport ?

Open in App

Solution

Active transport involves:
1. Use of energy
2. Movement against concentration gradient
3. Special membrane components.
Passive transport :
1. No use of energy
2. Movement along the concentration gradient
3. Any semi permeable membrane
Hence osmosis is a passive transport.
