The membrane around the vacuole Is known as:
Correct answer: A. Tonoplast
- A. Tonoplast
- B. Elaioplast
- C. Cytoplast
- D. Amyloplast
Explanation
The correct answer is Tonoplast. The tonoplast is the membrane that encloses the central vacuole in plant cells, similar to how the cell membrane surrounds the entire cell. It is essential for maintaining cell pressure, storage of nutrients, and waste management. The other options are incorrect because they refer to different organelles or non-existent terms: Elaioplast is for oil storage, Cytoplast is not a recognized term, and Amyloplast stores starch.
