Cellular Homeostasis starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Cellular Homeostasis.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9
A cell in an isotonic solution will __________.
A cell that cannot regulate its internal environment will likely __________.
A red blood cell placed in pure water will __________ due to osmosis.
Describe the difference between active and passive transport.
Describe the role of the sodium-potassium pump in maintaining cellular homeostasis.
Describe what happens to a plant cell placed in a hypotonic solution.
Describe what happens to animal cells in a hypertonic solution.
