3. A difference between a Prokaryotic and Eukaryotic cells is:
a. Prokaryotic cells are heterotrophs and Eukaryotic are autotrophs
b. Prokaryotic cells have DNA like a singular rubberband and Eukaryotic cells are like many separate spaghetti noodles.

d. Prokaryotic cells have cellulose and Eukaryotic have peptidoglycan
4. Sexual reproduction in the Protista is called:
a. copulation b. mitosis, c. conjugation, d. fission
5. Protista are all:
a. single celled, sexual/asexual b. multicellular, heterotroph/autotroph
c. eukaryotic, paracitic d. mobile, pathogenic
e. all of these charecteristics
6. Protozoans are classified by:
a. structures used for movement
b. color, structures, compounds
c. life cycle of the cell, reproductive structures
d. size and how they get their food
7. Which of these groups are all the organisms single cellular (no multicellular.)
a. Slimemolds b. Algae c. protozoans d. clorophytes e. all of them are
8. Some Protista live inside of another animal and actually help them. In fact, they help each other live. These are called:
a. paracites, b. symbiotic c. plasmodium d. vectors
9. Phagocytosis is when an amoeba:
