Vacuole in a plant cell
Correct answer: D. is membrane-bound and contains water and excretory substances.
- A. lacks membrane and contains air
- B. lacks membrane and contains water and excretory substances
- C. is membrane-bound and contains storage proteins and lipids
- D. is membrane-bound and contains water and excretory substances.
Explanation
A vacuole in a plant cell is a membrane-bound organelle that functions as a storage compartment. It contains water, nutrients, ions, and waste products. The central vacuole in plant cells is primarily filled with water and serves various purposes, such as maintaining cell turgidity and storing essential substances.
