Cytoplasm contents
Cytosol
Cytoskeleton
Organelles
Cytosol
The fluid portion, mostly water
Cytoskeleton
Provides structure
Organelles
Subcellular structures having characteristics shapes and specific functions
Plasma membrane
Protective barrier
Phospholipid bilateral
Part of the plasma membrane, this forms the cells outermost boundary, it contains a lipid bilateral and proteins
Selective permeability
Part of the plasma membrane, lipids act as a barrier to certain substances and proteins act as gatekeepers to certain molecules and ions
The role of proteins in the plasma membrane
Ion transport
Receptors
Enzymes
Linkers
Cell recognition
Carriers
Organelles
Centrosome
Cilia and flagella
Ribosome
Endoplasmic reticulum
Golgi complex
Mitochondria
Lysosomes
Peroxisomes
Proteasomes
Centrosome
Microtubule organizing Center
Cilia
Move substances
Flagella
Moves the cell
Ribosomes
Site of protein synthesis
Rough ER
Initial sorting and packaging into vesicles
Smooth ER
Synthesizes enzymes and fatty acids
Golgi complex
Adds carbohydrates and lipids. Packages further and sends out of the cell
Mitochondria
Produces ATP
Lysosomes
Digest worn out cell parts
Peroxisomes
Detoxify
Proteasomes
Break down proteins
The nucleus
Contains chromosomes, made of of DNA that contains genes. Control Center
Nuclear envelope
Double membrane that separates the nucleus from the cytoplasm
Nuclear pores
Numerous openings in the nuclear envelope, control movement of substances between nucleus and cytoplasm
