Protozoa

One-celled organism with no cell wall

Protozoa

Four main groups of protozoa

Flagellates, Ciliates, Amoebas, Sporozoans/Apicomplexans

The four groups of protozoa are based on

motility and structures used to move

Examples of Flagellates

Giardia, Tritrichomonas

Examples of Ciliates

Balantidium, Ichthyophthirius

Examples of Amoebas

Entamoeba histolytica / coli

Long whip-like or lash-like appendage

Flagellum

Tiny, short hairs over the body

Cilia

“False Feet”

pseudopodia

The 2 forms of Flagellates, Ciliates, and Amoebas

Motile Trophozoite, Resistant Cyst

pear shaped and possess at least 1 flagellum that allows Flagellates to move about in liquid

Motile Trophozoite

allows Flagellates to survive in adverse conditions in the external environment

Resistant Cyst

Flagellates swim in their host’s ?

body fluids

Which group of protozoans uses Asexual and Sexual reproduction

Sporozoans

What type of reproduction is used by the other 3 groups od protozoans

binary fission

Ciliates dart and twirl speedily in liquid media

Motile Trophozoite

Which group possess two types of nuclei

Ciliates

What two types of nuclei do Ciliates have

Macronucleus, Micronucleus

Amoebas glid along a solid surface, usually the bottom of a liquid medium

Motile Trophozoite

Poorly define, or blob-like, in shape

Amorphous

Most diverse of the groups and most complex life cycle

Sporozoans

Sporozoans move around via

undulations

The complex life style of Sporozoans include ? reproduction

asexual and sexual

What are the basic cell types of Sporozoans

sporulated oocyst or sporocyst, sporozoites, merozoites, gametes and zygotes
