what happens when cells (plant it animal) our place into hypotonic, hypertonic and isotonic solutions? (please tell me in your own words)
Answers
Answer:
# Animal cell:-
1. What happens when you place an animal cell in a hypotonic solution?
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. What happens when you place an animal cell in a hypertonic solution?
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. What happens when you place an animal cell in an isotonic solution?
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.
# Plant Cells:-
1. What happens when you place a plant cell in a hypotonic solution?
The water moves from a region of low osmolarity (extracellular fluid) to a region of high osmolarity (inside the cell). The cell would then expand. Unlike an animal cell, the plant cell does not burst. This is because plant cells have a rigid cell wall around the plasma membrane. Upon swelling with water they become turgid.
Hypotonic solutions keep vegetables like bell peppers crisp.
2. What happens when you place a plant cell in a hypertonic solution?
Water will leave the cell since the cell has a lower osmolarity than the extracellular fluid. As a result, the cell would shrink.
3. What happens when you place a plant cell in a isotonic solution?
The osmolarity of both fluids is equal. Though water diffuses in and out there is no net change in the volume of the cell.
