Protozoans

Protozoans. Single celled eukaryote (has a cell nucleus) that has some animal-like characteristics Many move about and feed like animals Most exist as a single cell and some live in groups called colonies Are found in the kingdom Protista. Need a moist environment to survive.

  1. Protozoans

  2. Single celled eukaryote (has a cell nucleus) that has some animal-like characteristics • Many move about and feed like animals • Most exist as a single cell and some live in groups called colonies • Are found in the kingdom Protista

  3. Need a moist environment to survive

  4. Groups of protozoans Ciliates • Move by waving tiny, hair-like organelles called cilia • Ex. Paramecium • It waves its cilia like tiny oars to move through the water • Also uses cilia to sweep food into its gullet

  5. Amoebas • Move by using pseudopods • Stretch its cytoplasm in the direction it will move • The stretched part becomes a pseudopod • The rest of the amoeba flows into the pseudopod • Also uses pseudopods to get food • Stretches out two pseudopods to surround a piece of food • The food is taken in to form a food vacuole

  6. Flagellates • Move using a whip-like organelle called a flagella • Are a combination of plant and animal • Contain chlorophyll and can make their own food like a plant • Can also eat other things like an animal • Ex) euglena

  7. Sporozoans • Do not have organelles for movement • Are parasites and live in the bodies of animals • An organism that lives in or on another animal (host) • Causes harm to their hosts • Ex) plasmodium which causes malaria • Transmitted by mosquitoes • When the mosquito bites, plasmodium gets into the blood and infects red blood cells • Infected blood cells eventually burst causing sickness and death
