Question

what happen when we put an animal cell into
i) hypotonic solution
ii) hypertonic solution
iii) isotonic solution
*only animal cell*​

Answer 1

Explanation:

i) Hypotonic solution:- If we keep a plant cell or animal cell in a hypotonic solution then the cell will be shrinking because the fluid goes from the high concentration to the low concentration.

ii) Hypertonic Solution:- If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).

iii) Isotonic Solution:- Isotonic solutions have the same water concentration on both sides of the cell membrane. Blood is isotonic.

Answer 2

1. Remember, water moves from a region of low osmolarity to a region of high osmolarity. In this case, since the extracellular fluid has low osmolarity, the water would rush into the cell. The cell would then expand and eventually lyse or burst.
2. In this case, water will leave the cell since the cell has a lower osmolarity than the extracellular fluid. As a result the cell would shrink in what is called plasmolysis.
3. The osmolarity of both fluids is equal. As such, though water diffuses in and out, there is no net change in the volume of the cell.
