The one which can tolerate highest external osmotic pressure is __________?
Correct answer: C. Fungi
- A. Algae
- B. Amoeba
- C. Fungi
- D. Bacteria
Explanation
Fungi can grow in environments with high external osmotic pressure because their rigid cell walls and compatible-solute mechanisms help them retain water. Amoeba is a likely alternative, but freshwater amoeba is especially vulnerable to osmotic water entry and must expel water using a contractile vacuole.
