Which of the following performs the same function as the contractile vacuole of a unicellular organism?
Answer Details
The kidney performs the same function as the contractile vacuole of a unicellular organism. Both the contractile vacuole and kidney are responsible for regulating the water content of the cell and the body, respectively. The contractile vacuole in unicellular organisms eliminates excess water from the cell, while the kidney in multicellular organisms eliminates excess water and other waste products from the body. This process helps to maintain the osmotic balance of the organism's internal environment.
