Cell Structure and Function

Prokaryotic Cells No nucleus No membrane-bound organelles

Eukaryotic Cells Membrane bound organelles Complex DNA

Organelles Nucleus – houses DNA, directs cell activity Golgi – packages and secretes products like proteins and lipids Mitochondria – place where energy is made ATP RER – studded w/ ribosomes, protein synthesis SER – lipid synthesis Ribosomes – site of translation, protein synthesis Cytoskeleton – maintains the shape of the cell Lysosome - filled with digestive enzymes that break down lipids, proteins, old organelles

Organelles Large vacuoles – water storage Cell Wall – rigid outer covering made of polysaccharides Chloroplasts – site of photosynthesis
