When an animal cell is placed in hypotonic environment, it will _
Correct answer: A. Undergo cytolysis
- A. Undergo cytolysis
- B. Undergo plasmolysis
- C. Be at equilibrium
- D. Its turgor pressure decreases
Explanation
An animal cell placed in a hypotonic environment will undergo cytolysis because water enters the cell due to the lower solute concentration outside the cell. This influx of water causes the cell to swell and eventually burst. Plasmolysis does not occur in animal cells and is relevant to plant cells in hypertonic solutions. Equilibrium does not apply here as the external solution is hypotonic, not isotonic. Turgor pressure is a concept applicable to plant cells, not animal cells, as animal cells lack a cell wall.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
