Cohesion is the property of water molecules which shows its hydrogen bonding. Surface tension is the phenomenon of holding together of water molecules.
Name the term which is given for the movement of water through a semipermeable membrane?
A.
Diffusion
B.
Osmosis
C.
Tonicity
D.
Transpiration
Answer: Option B
Explanation:
Osmosis is a specialized form of diffusion, which involves a passive movement of water from higher to lower concentration of water with the help of a semipermeable membrane.
What is the measure of the osmotic pressure gradient of solutions separated by a semipermeable membrane?
A.
Water potential
B.
Ficks law
C.
Turgor pressure
D.
Tonicity
Answer: Option D
Explanation:
Osmotic pressure gradient of two solutions is measured by tonicity. There are three different types of tonicity which a solution can have with respect to other solution: isotonic, hypotonic, and hypertonic.
Name the condition in which protoplast of the plant cell shrinks away.
A.
Turgid
B.
Plasmolysis
C.
Flaccid
D.
Rigid
Answer: Option B
Explanation:
Plamolysis is the condition of the cell which causes the shrinkage of protoplast, when the cell is placed in the hypertonic solution i.e., water moves out of the cell.
