⩥ Eukaryotic Cells. Answer: Contain nucleus membrane, genetic
material in nucleus, multicellular, membrane-bound organelles.
⩥ Ribosomes in Cells. Answer: Prokaryotic: free 80s, Eukaryotic:
attached to Rough ER 70s.

conditions, form during sporulation.
⩥ Chemotaxis. Answer: Movement with chemical gradient.
⩥ Phototaxis. Answer: Movement toward/away from light.
⩥ Bacterial Flagella. Answer: Promote movement in bacteria.
⩥ Fimbriae. Answer: Protein structures for cell attachment.
,⩥ Pili. Answer: Similar to fimbriae, aid in attachment.
⩥ Vegetative Cells vs. Endospores. Answer: Typical cell state vs.
dormant protective state.
⩥ Sporulation Process. Answer: Cells form endospores in hostile
environments.
