Study Notes
Prokaryotic Cell Structure and Function
- The nucleoid is a region in the cell where genetic material (DNA) is concentrated, but not bounded by a membrane.
- The peptidoglycan layer, also known as the murein layer, provides resistance to phagocytosis and adherence to surfaces.
- The periplasmic space is a region between the plasma membrane and the peptidoglycan layer, where enzymes involved in cell wall synthesis and degradation are located.
- Flagella provide motility to prokaryotic cells, allowing them to move towards or away from stimuli.
- The plasma membrane serves as a selective barrier, controlling the movement of substances in and out of the cell, and also provides a site for metabolic reactions.
