vacuole

This is done by pulsation of the vacuole, which ultimately bursts, passing fluid waste to the outside.

These masses of food seem to be inclosed within a little area containing fluid, called a vacuole.

Waste nitrogenous products formed within the cell when work is done are passed out by means of the contractile vacuole.

Spores with two polar-capsules, and without an iodinophilous vacuole in the sporoplasm.

Contractile vacuole absent; the nucleus is spherical and contains many large chromatin granules.
