Cell Structure and Function

Plasma membrane: Regulates what enters and exits the cell.
Nucleolus: Responsible for ribosome production.
Smooth endoplasmic reticulum (SER): Synthesizes lipids and detoxifies harmful substances.
Mitochondria: Produce ATP through cellular respiration.
Ribosomes: Involved in protein synthesis.
Rough endoplasmic reticulum (RER): Involved in protein synthesis.
Golgi apparatus: Packages and ships proteins.
Lysosome: The cell's "digestive system", breaking down substances.
Tight junctions: Prevent substances from leaking between cells.
Phospholipid bilayer: Composed of two layers, with hydrophilic heads and hydrophobic tails; regulates what enters/exits the cell.
Peroxisomes: Breakdown fatty acids and detoxify substances.
Microtubules: Provide support, assist in cell division and intracellular transport.
Cilia: Move substances across the cell surface.
Osmosis: Movement of water across a semipermeable membrane.
Active transport: Requires energy (ATP) to move substances against their concentration gradient.
Endocytosis: Engulfing of extracellular material by the cell membrane.
Sodium-potassium pump: Moves potassium into and sodium out of the cell; important for generating electrical signals.
Ribosomes: Composed of RNA and protein.
Diffusion: A type of passive transport, movement of molecules from high to low concentration.
Passive transport: Processes like diffusion and osmosis that don't require energy.
Gap junctions: Allow direct communication between adjacent cells.
