Two contractile vacuoles regulate osmotic pressure (see Osmosis) and also serve as excretory structures. A paramecium has a large nucleus called a macronucleus, without which it cannot survive, and one or two small nuclei called ... Although this four-kingdom system advocated herein has the greatest advantage,

It is only larger and more complex organisms that require a circulatory system to transport substances around the body. The amoeba, which is a single-celled animal, does not require a transport system because it is able to exchange all the substances it needs directly across its thin cell membrane.
