Which cell feature is responsible for storing water ?

The correct answer is A. Vacuole.

A vacuole is a membrane-bound sac that stores water, nutrients, waste products, and other materials in the cell. It is the largest organelle in plant cells, and it can also be found in animal cells.

A lysosome is a membrane-bound organelle that contains digestive enzymes. It is responsible for breaking down and recycling materials in the cell.

A mitochondrion is a membrane-bound organelle that produces energy for the cell. It is often called the “powerhouse of the cell.”

None of the above options are responsible for storing water.
