Term
Cytoskeleton
Definition
Description: Components are made of protein. Includes
a. Microfilaments
b. Intermediate Filaments
c. Microtubules

Function: Reinforces cells shape, functions in cells movement
Term
Mitochondria
Definition
Description: Located throughout the cytoplasm.

Function: Cellular respiration occurs here as well as the generation most ATP
Term
Lysosome
Definition
Description: Located throughout the cytoplasm. Only found in animal cells.

Function: Digestive organelle where macromolecules are hydrolyzed.
Term
Golgi Apparatus
Definition
Description: Located in the cytoplasm, next to the ER.

Function: It is the organelle active in synthesis, modification, sorting and secretion of cell products.
Term
Ribosomes
Definition
Description: Found in throughout the cytoplasm, attached to the rough ER, or nuclear envelope.

Function: Complexes that make proteins.
