Study Notes

Prokaryotic Cell Structures

Pili: Hair-like appendages that facilitate bacterial attachment to surfaces and other cells; crucial for DNA transfer between bacteria.
Flagellum: A whip-like structure that enables mobility in prokaryotic cells, allowing for movement towards or away from stimuli.
Nucleoid: Central region in prokaryotic cells where DNA is located; not surrounded by a membrane, distinguishing it from eukaryotic cell nuclei.
Cytoplasm: Gel-like substance filling the cell; contains organelles and is the site for many cellular processes.
Capsule: Protective outer layer covering the cell wall in some prokaryotes; aids in evading the host immune system and enhances bacterial adherence.
Cytoplasmic Membrane: Semipermeable layer that encloses the cytoplasm; regulates the movement of substances in and out of the cell, maintaining homeostasis.
Cell Wall: A sturdy, fibrous layer surrounding the cytoplasmic membrane; provides structure and protection against mechanical stress and osmotic pressure.
Ribosomes: Molecular machines responsible for protein synthesis, vital for cell function and growth.
