GUIDE
⫸ Biochemistry Answer: The study of the chemistry of life at the
molecular level
⫸ Bacterial Cell (4) Answer: - DNA is freely in the cytoplasm (no
membrane - nucleoid)
- Some contain a cell wall
- Some contain flagella
- No organelles
⫸ Animal Cell (3) Answer: - Contains a nucleus (has DNA) that is
surrounded by a membrane
- No cell wall
- Contains membrane bound organelles
⫸ Plasma Membrane (3) Answer: - The periphery of the cell (made up
of lipids & proteins)
- Hydrophobic (repels water), thin, & flexible
- Hydrophilic things enter through membrane proteins (channels,
receptors, & pumps)
