Protist Notes
Protists are:
1. eukaryotes
2. not in plant, animal, or fungi kingdoms.
3. most unicellular
4. 1st eukaryotesdate back at least 1.5 billion years
Protist Movement
1. Changing Shape
2. Special organelles
3. Don’t move actively
1. Amoeboid movement: change shape with cytoplasmic projections:
pseudopods - false feet
2. Special Organelles: assist movement
Cilia - Short and numerous
Move like oars on a boat
Ciliates - paramecium
Flagella Long and only a few per cell
Produce a wavelike motion
. Passive Flagellates – Euglena
3 Passive movement: depend on air/water currents or other organisms. - Plasmodium
Protist Reproduction
Mitosis – asexual (amoebas)
Conjugation – sexual (paramecia)
Alternation of generations - asexual and sexual (water “mold” or slime “mold”)
sporangium: asexual spores
Ecology of Protists:
Autotrophic Protists: photosynthesize – phytoplankton, red and brown algae
Heterotrophic Protists: engulf and digest their food – Amoebas, ciliates(paramecia) and Slime “molds”
Symbiotic Protists:
Mutualists: symbiosis in which both the protist an host benefit – Trichonumpha and termites
Parasites: protist benefits and the host is harmed – Giardia and Humans, African sleepng sickness, Malaria
Animal-like Protists: Protozoans
Animal-like protists are classified by their means of movement
Ciliates - paramecium.
Zooflagellates: Animal-like protists that swim using flagella live in the lakes and streams and in bodies of other
organisms
Flagella: long whiplike projections moving cell
funguslike protists obtain their food: by external digestion: parasitism or decomposition
Misc.:
A food vacuole is a small cavity in the cytoplasm that temporarily stores food
Phylum Sarcodina: Foraminiferans: amoeba like
As foraminferans die, the calcium carbonate from their shells accumulates on the ocean bottom
The name "heliozoan" means “sun animal”
