Question
is the membrane covering the vacuole: a. tonoplast b. cell membrane c. cell sap d. none
Correct Answer
Option A is the correct answer.
Detailed Explanation
In plant cells, the large central vacuole is surrounded by a single membrane called the tonoplast. It regulates the movement of ions and other molecules between the cytoplasm and the vacuolar sap.
Hint
This membrane's name sounds like it's for 'tone' or pressure, which the vacuole helps maintain.
