Flashcards in Protista Deck (13):
1

Protists

Simplest eukaryotic organisms

2

Heterotrophic Protists

amoeba, paramecium

3

Autotrophic protists

Euglena, algae

4

Fungi-like Protists

Slime molds

5

Amoeba

-Pseudopods(Move and change their shape through changes in their cytoskeleton and streaming of cytoplasm)
-Heterotrophs
-Phagocytosis

6

Phagocytosis

-Pseudopods engulf food and internalize the food to digest it in vacuoles in the cytoplasm
-Amoeba

7

Protist Digestion

Intracellular Digestion

8

Paramecium

-Cillia
-Heterotroph
-Defined shape

9

Euglena

-Autotroph
-Have a red eyespot to locate light
-Photosynthesis
-Flagellum

10

Paramecium Digestion

-Contractile vacuoles that remove excess water
-Food is internalized through an oral groove and cytopharnx
-Vacuole breaks off into cytoplasm and goes toward the anterior of cell
Solid wastes expelled at anal pore

11

Protozoa's adaptations for absorption?

Digested food in the food vacuole passes by simple diffusion into cell cytoplasm

12

Circulation in Protozoans

-Materials pass by simple diffusion across the membrane and streaming of cytoplasm within the cell (cyclosis)

13

Excretion in Protozoans

Diffusion
