Bacteria, Archae, and Algae organisms

Most protozoa are ___________

heterotrophic

lives in termite intestines

Trichonympha

a pathogen which causes STDs

Trichomonas

a pathogen, transmitted by an insect vector, causes African Sleeping Sickness

Trypanosoma

group of mostly marine amoeboid protozoans. Part of

“floating life” called plankton in the ocean. Calcareous shells

Foraminiferans

among the oldest protozoa, another

group of mostly marine amoeboid protozoans. Part of “floating life” called plankton in the ocean. Silica shells.

Radiolarians

free-living, sweeps nutrients (bacteria, algae etc.) into an oral groove upon which food vacuoles form.

Paramecium

Asexual reproduction

Binary fission

Sx reproduction

Conjugation

infects cats and other domestic animals. Contact with infected feces may result in transmission to humans, nonmotile

Toxoplasma

Causes malaria

Plasmodium

lives in freshwater. The eyespot senses light and the single flagellum helps move the organism

toward it.

Euglena

Most species have two flagella that result in a spinning or twirling motion.

Dinoflagellate

Also known as golden algae, Mostly unicellular (some colonial) marine algae with cell walls arranged as valves made of silica.

Diatoms

Help buoyancy

air bladders

colonial green algae found in freshwater. Colonies are composed of hundreds to thousands of flagellated cells that form a hollow sphere.

Volvox

Vegetative cells carry out asexual reproduction to form _________

daughter colonies

filamentous (colonial) organisms seen in a thread-like line in the water.

Spirogyra

multicelluar green algae found in marine and brackish. Often called “sea lettuce” because of the likeness of the blades to lettuce leaves.

Ulva

Photoautotrophic (photosynthetic) and able to fix nitrogen in special cells called heterocysts. from the Domain Bacteria, group Cyanobacteria

Nostoc

Photoautotrophic (photosynthetic) example from the Domain Bacteria, group Cyanobacteria

Oscillatoria
