Which of the following organelles helps to remove excess water from cells?

The organelle that helps to remove excess water from cells is the contractile vacuole. This organelle is found in many single-celled organisms, such as amoebas and paramecia, as well as in some specialized cells in multicellular organisms. The contractile vacuole works by pumping excess water out of the cell and into the environment. This is important for maintaining the proper balance of water and other substances within the cell, and for preventing the cell from bursting due to osmotic pressure. The other organelles listed, such as mitochondria, ribosomes, Golgi bodies, and nuclei, do not have a direct role in removing excess water from cells.
