Protists Review: Locomotion and Nutrition (Chlorophyta to Ciliophora)

Vocabulary flashcards covering key protists, their locomotion, nutrition, and plant/animal/fungi-like classifications from the lecture notes.

Chlorophyta (green algae)

Locomotion: flagella; Nutrition: autotrophic; plant-like protists.

Amoebozoa (amoebas)

Locomotion: pseudopods (pseudopodia); Nutrition: heterotrophic; animal-like.

Pseudopods (pseudopodia)

Extensions of cytoplasm used by certain protists (e.g., amoebas) for movement and feeding.

Slime molds

Fungus-like protists; heterotrophic; include plasmodial slime molds and cellular slime molds.

Plasmodial slime mold

Fungus-like protist that forms a multinucleate plasmodium; moves by cytoplasmic streaming; heterotrophic.

cellular slime mold

Fungus-like protist composed of discrete cells; individual cells can move or aggregate; heterotrophic.

Diatoms

Autotrophic protists with silica-based cell walls; photosynthesize; plant-like.

Actinopoda (Radiolarians)

Move with ray-like pseudopods (axopodia); skeleton made of silica or related materials.

Rhizopoda (Amoebas)

Move with lobed pseudopods; typically lack a shell; heterotrophic; animal-like.

Dinoflagellates

Move by flagella; mixotrophic (some autotrophic, some heterotrophic); plant-like; can cause bioluminescence and red tides.

Ciliophora (Ciliates)

Move by cilia; heterotrophic; animal-like.

Autotroph

Organism that makes its own food from inorganic sources (e.g., photosynthesis in chlorophytes).

Heterotroph

Organism that obtains food by consuming other organisms; includes many protists and fungi-like forms.
