How fast can a paramecium swim?
Their speed of motion is about four times their own length per second.
Plasmodium falciparum is a disease causing protozoan that harms a human host. This classifies this organism as a ______________.
parasite
The __________ can be any shape it wants because its ___________ is flexible.
amoeba, cell membrane
What are the tiny cellular structures that allow a paramecium to swim?
Small, hair-like projections of the cytoskeleton called Cilia.
How many nuclei does a paramecium have? Can you describe their functions?
Paramecium have a macronucleus to hold chromosomes it needs to make proteins and a micronucleus for sexual reproduction.
The long, whip-like tail that allows this euglena to swim is called a _______________.
flagella
Plasmotomy allows protozoans to go through binary fission and make a clone of themselves. This process is similar to ___________ in human cells.
mitosis
What is the difference between autotrophic and heterotrophic protozoa?
The autotrophic protozoa can produce their own sugar, they can photosynthesize. Heterotrophic protozoa must eat other organisms or decompose dead organic matter
The black lines in this picture are pointing to _________________ which keep this paramecium from exploding due to ____________ by ______________.
contractile vacuoles.......water entering.........osmosis
Volvox is a great example of individual, single celled organisms living together in a _______________.
colony. These protists are often mistaken for being multicellular. They can live independently but want to form a big group for protection.
A paramecium uses its _________________ to eat ______________.

This little, green euglena can ______________ because it contains a green chemical known as _______________.
photosynthesize (make its own sugar)....chlorophyll
In this picture what is happening to this amoeba's dinner? Be specific! What cell organell will be created from the psuedopodia?
The pseudopodia will merge together to make a food vacuole.
How does an amoeba move?
It can push its cytoplasm into extensions of its cell membrane to make pseudopodia.
