Choose the correct answer from each of the four options given below :

The correct option is A Endosmosis
The correct option is A:
Explanation of the correct option:
- Endosmosis is the inward diffusion of water molecules from a region of higher water potential to a region of lower water potential through a semipermeable membrane.
- Endosmosis occurs due to differences in osmotic concentrations.
- Water enters the body of fish by endosmosis because tap water act as a hypotonic solution with high water potential as compared to the fish body.
- As a result, the fish begin to enlarge, reaching a point when their bodies rupture and they die.
Explanation of the incorrect options:
Option B:
Exosmosis is the outward movement of water molecules from a region of low solute concentration to a region of high solute concentration.
Option C:
Diffusion is the movement of molecules from a region of high concentration towards a region of low concentration.
Option D:
Plasmolysis is the process of water loss from the cell when placed in a hypertonic solution which leads to the contraction of the protoplast.
Final answer: The inward movement of water molecules due to endosmosis leads to the bursting of the body of a marine fish.
