Granules can be stained to aid in bacterial identification.
What is the cytoskeleton?
Cellular scaffolding or skeleton within the cytoplasm
The cytoskeleton provides structural support to the cell.
What are ribosomes made of?

*found within cytoplasm or attached to plasma membrane
How many subunits do ribosomes have?
Two subunits
Cell have thousands of it
What does the plasma membrane do?
Separates the cell from its environment
What is the orientation of phospholipid molecules in the plasma membrane?
Hydrophilic heads directed outward and hydrophobic tails directed inward
*proteins embedded in two layers of lipids(lipid by layer)
What are the two main types of bacterial cell walls?
Gram-positive and Gram-negative
What’s the function of cell wall?
Provides rigid support while freely permeable to solutes
