WHAT IS

PROTOZOA oldest known group of heterotrophic life

one-celled; smallest of animals

live in water or damp areas

Page 5: Protozoa

System Type Protozoas System

Muscular-Skeletal No inner or outer skeleton.

Digestion Takes in food via the water and stores the food in sacs called vacuoles. They eat tiny algae and bacteria.

Nervous Has a very low level reaction to the world around it and does not have a brain per se. They can react to light and temperature changes.

Circulation Has water flow in through the pores. The water contains the food and oxygen the protozoa needs.

Respiration Takes in oxygen through the cell membrane and gives off carbon dioxide through the cell membrane.

Reproduction Reproduces by splitting in half (fission)Excretion Vacuoles take in and get rid of water.

Symmetry Usually asymmetrical.Coloration Very microscopic and is pale in color generally.

SPOROZOA commonly parasitic on

vertebrate animals. best-known sporozoan:

plasmodium invade red blood cells

where they multiply, eventually escaping from the ruptured cells

CILIOPHORA complex freshwater or

saltwater protozoans swim by the

coordinated beating of their cilia (short, hairlike structures that cover the cell surface.)

Best-known ciliate: paramecium
