Protista Flashcards
1
Q
Protists
A
Simplest eukaryotic organisms
2
Q
Heterotrophic Protists
A
amoeba, paramecium
3
Q
Autotrophic protists
A
Euglena, algae
4
Q
Fungi-like Protists
A
Slime molds
5
Q
Amoeba
A
- Pseudopods(Move and change their shape through changes in their cytoskeleton and streaming of cytoplasm)
- Heterotrophs
- Phagocytosis
6
Q
Phagocytosis
A
- Pseudopods engulf food and internalize the food to digest it in vacuoles in the cytoplasm
- Amoeba
7
Q
Protist Digestion
A
Intracellular Digestion
8
Q
Paramecium
A
- Cillia
- Heterotroph
- Defined shape
9
Q
Euglena
A
- Autotroph
- Have a red eyespot to locate light
- Photosynthesis
- Flagellum
10
Q
Paramecium Digestion
A
-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
Q
Protozoa’s adaptations for absorption?
A
Digested food in the food vacuole passes by simple diffusion into cell cytoplasm
12
Q
Circulation in Protozoans
A
-Materials pass by simple diffusion across the membrane and streaming of cytoplasm within the cell (cyclosis)
13
Q
Excretion in Protozoans
A
Diffusion
