PROTOZOA
plasmodium protozoa
WHAT IS
PROTOZOA oldest known group of heterotrophic life
one-celled; smallest of animals
live in water or damp areas
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.

plasmodium invade red blood cells
where they multiply, eventually escaping from the ruptured cells
