Amebas (not a phylum) |
Protozoans with pseudopods |
|
|
Amoeba (genus) |
Found on bottom of freshwater ponds Contain lobopodium |
|
|
Amoeba (genus) |
Ectoplasm(gel-like and clear, no organelles) Endoplasm( fluid-like and darker, organelles) Contractile Vacuole Food Vacuoles Lobopodium |
|
|
Foraminifera |
Marine amebas with chambered tests made of calcium
|
|
|
Radiolarians |
Marine amebas with tests made of silica; thin pseudopods can be extended through small pores |
|
|
Phylum Euglenozoa |
Flagellated protozoans |
|
|
Euglena |
in phylum euglenozoa; autotrophs and heterotrophs; |
|
|
Euglena |
Contain chloroplasts Stigma/eyespot (allows light in) Flagellum |
|
|
Trypanosoma |
In phylum euglenozoa; flagellated, heterotrophic; Can cause African Sleeping Sickness which is transmitted by the tsetse fly; Contains an undulating membrane |
|
|
Phylum Chlorophyta |
spherical colony of somatic cells cover the surface of a gelatinous ball; Somatic cells contain chloroplasts and a pair of flagella; protoplasmic strands occur between cells; daughter colonies occur inside large mother colony and contain asexual production |
|
|
Phylum Chlorophyta |
Zygotes are formed sexually by adult colonies and contain a spiny case which provides protection to the zygote after the adult colony disintegrates in the winter. In spring the zygotes break out of spiny case and undergo cell division to form new colonies |
|
|
Phylum Retortamonada |
Contains class: Giardia |
|
|
Giardia |
In phylum retortamonada; binucleate, tear-drop shaped cell |
|
|
Phylum Apicomplexa |
all endoparasites |
|
|
Plasmodium |
in phylum apicomplexa; causes malaria; leads to signet ring stage (trophozoite) in RBCs |
|
|
Phylum Ciliophora |
contain cilia and are multinucleate(contain a macronucleus and a micronucleus) |
|
|
Paramecium |
In Phylum Ciliophora; |
|
|
Paramecium |
contain cilia; contractile vacuole with radiating canals (osmoregulation); trichocysts can be undischarged oval structures beneath membrane or discharged to function as defense; Oral groove leads to the cytostome(mouth) which empties food into a food vacuole; macronucleus and micronucleus |
|
|
Paramecium Binary Fission |
asexual form of reproduction; one cell pinches into two |
|
|
Paramecium Conjugation |
sexual reproduction; micronuclei are exchanged to exchange genetic material (no increase in number of protozoa tho) |
|
|
Didinium |
in phylum ciliophora; carnivorous protozoan that feeds on paramecium and other protozoan; contains 2 bands of cilia and cystostome (mouth) and contractile vacuole |
|
|
Vorticella |
in Phylum Ciliophora; has stalked cilia (the stalk is contractile and usually anchored) cilia around the edge of peristome (mouth) |
|
|
Phylum Dinoflagellata |
typically have 2 flagella:one in a groove along the "equator" and another in a groove perpendicular to the equatorial groove; primary producers that are part of a group called plankton |
|
|
Plankton |
drift in lakes and oceans and those that can photosynthesize are called phytoplankton and make up the base of aquatic food chains |
