Subkingdoms: Protozoa and Algae
Protozoa
Exist single-celled individuals
Most heterotrophic
Most have means of movement
Phylum
Sarcodina
Mastigophora
Ciliophora
Sporozoa
Algae
Exist in colonies of single celled organisms
Most autotrophic
Most just float along with the currents
Protozoa
Characteristics
No standard body shape.
Movement by pseudopod.
Heterotrophic.
Can be pathogenic.
Movement by one or more flagellum
(flagellate).
Both autotrophic AND saprophytic.
Often has a characteristic red eye-spot (light sensitive region)
Can be pathogenic.
Movement by cilia
Can be large.
Range in body shape from cone-shaped, bellshaped, foot-shaped.
Mostly fresh water organisms.
Most heterotrophic.
Often contain large macronucleus.
Reproduce through simple cell division although they can share DNA through conjugation.
Can be pathogenic.
No means of transportation.
Very large phylum -30000+
All pathogenic (parasitic).
Forms a spore at some point in life cycle.
Organisms transported via insects like mosquitos and flies.
Example organism
Amoeba
Euglena
Volvox - these are colonial (form colonies) and have 2 flagellum
Paramecium
Stentor - trumpet shaped.
Plasmodium - cause of malaria.
