|
Protist - Apicomplexansare all parasites
some cause serious human diseases One end, the apex,contains a complex of organelles specialized for penetrating a host Most have sexual and asexual stages that require two or more different host species for completion Example: Plasmodium - causes malaria |

Amoebozoansare amoeba that have lobe-or tube-shaped, rather than threadlike, pseudopodia They include gymnamoebas, entamoebas, and slime molds |
|
|
Group Radiolaria
|
Marine protists called radiolarians have tests fused into one delicate piece, usually made of silica (SiO2)
|
|
|
Group Foraminiferans
|
Protists - Shelled amoebas
Example: Foraminifera Foraminiferans, or forams, are named for porous, generally multichambered shells, called tests Pseudopodia extend through the pores in the test |
