Protozoans Flashcards
Protozoans are:
- Unicellular
- Endoplasm and ectoplasm
- contains vacuoles
- contains more than 1 nucleus
- Locomotion (Pseuodopodia, Flagella, Cilia(
- Attachment
In Endoplasm
Connects the nucleoplasm to the endoplasm
a. Karyosome
b. Contractile Vacuoles
c. Nuclear membrance
c
In Endoplasm
Single mass of granules that may be near the center of the cell or at times being surrounded by chromatin particles
a. Karyosome
b. Contractile Vacuoles
c. Nuclear membrance
a
In Endoplasm
