1. Ch 2.1 : Protozoa Animal Like
Presented by Mr.Mulligan,
7w Science

2. Protists Wide variety of organisms
One celled or multi-celled. Can be plant like, animal like, fungus like.
May or may not contain chlorophyll
Eukaryotes (have a nucleus)

3. Protozoa 1 cell and contains organelles No chlorophyll
times bigger than bacteria but still microscopic
If Bacteria was the size of your shoe, Protozoa would be the size of a football field!

4. Protozoa

5. Where do they live? Oceans, fresh water and damp soil
In other organisms (parasites)
They will feed on dead organisms, monerans or other protists.

6. What do they eat?
Protozoa will feed on dead organisms, monerans or other protists.

7. 4 Main Groups: Sarcodines Ciliates Flagellates Sporozoans
How do you think they were classified into these 4 groups?

8. Sarcodines Pseudopods = “false foot” Moves by changing shape
Traps food by making a vacuole around it
For example: Amoeba

9. Ciliates Cilia = short, hairlike extensions Fastest moving protozoa
Like bumper cars: speed, bump into something, reverse direction
Cilia help sweep food into ‘oral groove’
For example: Paramecium

10. Flagellates Long, whiplike flagella (pl.), flagellum (sing.)
Tend to be parasites in blood
Some are good: help termite digest wood
Some are bad: cause African sleeping disease
For example: Euglena

11. Sporozoa Cannot move on their own Are all parasites
Malaria attacks red blood cells, reproduce and burst out of cells to infect another
For example: Malaria
