Which of the following terms is used to describe the membrane of central vacuole?
Correct answer: A. Tonoplast
- A. Tonoplast
- B. Myoplast
- C. Periplast
- D. Epi Tonoplast
Explanation
Option A: Tonoplast is the membrane that surrounds the central vacuole in plant cells. It is a single layer of phospholipids that is selectively permeable, allowing certain molecules to pass through while preventing others from doing so. This allows the central vacuole to maintain a different composition of solutes than the rest of the cell. Option B: Periplast is the outer membrane of a cell. It maintains the cell's shape and protects it from the environment. Option C: Myoplast is a term used to refer to the mitochondria in muscle cells. It produces energy for the cell. Option D: Epitonoplast is a non-existent term. There is no membrane that sits on top of the tonoplast.
