Found in plant cells, very important to cell function.

Used for storage and to maintain water balance

Storage- stores dissolved substances important to the cell

Water balance- a central vacuole’s membrane maintains tonicity, which allows expansion and contraction

Vacuole means blank space

Surrounded by a tonoplast

Found in some protists

Used to pump water and maintain water balance in the cell

1. A central vacuole’s membrane is also called a:A. storage membraneB. tonoplastC. cell wallD. microtubule

2. Plant cells increase and decrease their size by increasing their:A. nucleusB. cytoplasmC. central vacuoleD. contractile vacuole
