Protists: What are they?
Protozoans
Animal-like Protists

Characteristics
 Heterotrophs-
consume food
 Move from place to place
 Unicellular (one celled)
 4 groups based on how they move
Protozoans
Sarcodines

Sarcodines
Have pseudopods (cell bulge movement)
 Contractile vacuoles- remove extra water from the
cells
 Also have:






Cytoplasm
Food vacuole (breaks down food)
Nucleus
Cell membrane (very thin and flexible so no definite shape)
Example: Amoeba
Turn to Amoeba Drawing and Label

Ciliates have:
Protozoans
Ciliates
Cilia- long hairlike projections that move with wavelike
motion
 Contractile vacuoles (collect excess water from cytoplasm)
 Large and small nucleus
 Cytoplasm
 Oral groove (used to move water containing food to vacuole)
 Food vacuole (food is broken down and distributed here)
 Pellicle (stiff, flexible covering)
 Anal Pore (wastes leave here)


Example: Paramecium
Turn to Paramecium drawing and
label
Protozoans
Sporozoans

These are characterized as
 Parasites
(live off of another living thing)
Move by flagella, hosts, or slime
 Example

 Plasmodium
 Causes
Malaria- moves from person to person by
mosquito
Protozoans
Flagellates

Have a
 Long
whip-like flagella to move
 Example
 Giardia
Plant Like Protists
Autotrophs- make their own food through
photosynthesis and therfore have Chloroplasts
 Examples:

Diatoms: glass-like with cell walls
 Euglenoids: Euglena---which is autotrophic but can
also be heterotrophic when no sunlight is available
 Dinoflagellates- always have 2 flagella



when they move, the dinoflagellate twirls like a toy top
Red, Green, & Brown Algae: seaweeds
Euglenoid- turn to euglena page and

Red, Brown and Green Algae
Fungus-Like Protists

Like a fungus because they:




Un-like fungus because they:


Are heterotrophs
Have cell walls
Use spores to reproduce
Move at some point in their life cycle
Examples:
Slime molds
 Water molds
 Downy molds
