Functions of cell
- store and receive genetic information
- produce biological molecules
Functions of organelles
Cell membrane - retain cell contents and control exchange of substances
Centrioles - assemble spindle when nucleus divides to move chromosomes
Chloroplasts - site of reactions of photosynthesis
Golgi body - modifies and packages protein; makes secretory vesicles and lysosomes
Lysosomes - enzymes destroy old parts of cell and digest food particles and beacteria
Mitochondria(pl) - site of aerobic respiration
Nuclear envelope - allows movement between cytoplasm and nucleus
Nucleolus - produces ribosomes
Nucleus - contains store of genetic information
Ribosomes - assemble amino acids to make proteins
Rough endoplasmic reticulum - transport proteins to golgi body
Smooth endoplasmic reticulum - makes cholestrols, triglycerides and phospholipids
