Lab 9: Protists

Flashcards covering key concepts from the Lab 9 lecture on Protists.

Protist

A diverse group of eukaryotic microorganisms, often classified in various supergroups.

Autotrophic

Organisms that produce their own food, typically through photosynthesis.

Heterotrophic

Organisms that obtain food by consuming other organisms. Includes phagocytic and absorptive types.

Cilia

Short hair-like structures used for movement in some protists.

Flagella

Long whip-like structures used for movement in some protists.

Pseudopodia

Temporary projections of eukaryotic cells used for movement and feeding.

Unicellular

Organisms composed of a single cell.

Filamentous

Organisms that form long, thread-like structures.

Colonial

Organisms that live in groups, often composed of many cells.

Multicellular sheet

Organisms that form a flat layer of cells.

Trypanosoma

phylum kinetoplastea

sleeping sickness

tsetse fly

Plasmodium

A genus of parasitic protists that causes malaria.

Spirogyra

A green algae known for spiral-shaped chloroplasts and reproductive conjugation.

Volvox

A colonial green algae characterized by its flagellated cells forming spherical colonies.

Diatoms

A type of algae known for their intricate silica shells or tests.

Brown Algae

Multicellular macroalgae that include species such as kelp, belonging to the Phylum Phaeophyta.

Red Algae

Multicellular algae found in marine environments, belonging to the Phylum Rhodophyta.

Ciliophora

A phylum of protists characterized by the presence of cilia.

Amoebozoa

A phylum of protists that move and feed using pseudopodia.

Apicomplexa

A phylum of parasitic protists; includes Plasmodium, the malaria-causing organism.

crustose - Grow horizontally and form a thin sheet or crust over the surface on which they are found

Foliose - Form more broad leaf-like or lobed structures that extend above the surface on which they are found

Fruticose - form more elaborate structures that may be finely branched with fruiting-like
bodies
