Protista;
-are eukaryotic
-are both multi and single cellular
-are both micro and macroscopic
-are both auto and heterotrophic
Groups:
-protozoa
-algae, plant-like, auotrophic, photosynthetic
-fungi, absortion/heterotrophic
Protozoans;
-unicellular
-heterotrophic
-asexual reproduction
Amoeba, Phylum Rhizopoda, do not have cell walls. They
are pseudopods, filled with cytoplasm, and mostly live in fresh or salt water. The marine protozoans have shells made of
silicon. They use diffusion for their gas exchange.
Flagellates, Phylum Zoemastagino, have one or more flagellates.
Some live in termites gut and break down the food. They can cause the African sleeping sickness which is carried by the tee-tee
fly.
Cilliates, Phylum Ciliaphera (paremesium), reproduce
asexually and live in aquatic habitats. Their body plan includes a cilia, oral groove, and gullet.
Sporozoans, Phylum Sporazoa, are all parasites. They
produce a spore which is the product of a cell.
Algae;
-are photosynthetic
-are autotrophic
-have many different pigments
Phytoplankton-
- Euglenoids, Phylum Euglinophyta
-unicellular
-aquatic
-protein pelicle surrounding them
-auto or
heterotrophic~ depends on enviroment
-cannot see but can detect light
- Diatoms, Phylum Bucillenphyta (Golden algae)
-unicellular
-photosynthetic
-chlorophyll
and carotemplites
- Dinoflagellates, Phylum Dinoflagellata
-two
flagellas
-cell walls made of cellulose
-red pigments
- Red Algae, Phylum Rhotophyta
-multicellular
-absorb
green, blue, and violet wavelengths
- Brown Algae, Phylum Phaeophyta
-kelp can grow
to 60 cm
-used as a thickener in shakes at fast food places
-multicellular
-marine
- Green Algae, Phylum Chlorophyta
-7,000 species
-multi,
uni, and colonialcellular
-used in food products
-sexual and asexual
~gave rise to plants
- Fungus like protists
-absortion
