Cell Structures and Functions Flashcards
Cell membrane
Facilitates the exchange of nutrients and waste materials
Cytoplasm
Provides cellular nutrition and supports organelles
Organelles
Carries out the maintenance and functions of the cell
Endoplasmic reticulum (roadways)
Synthesizes proteins and lipids; metabolizes carbohydrates and steroids; regulates calcium concentration; protein transport
Ribosomes (protein factories)
Synthesizes proteins
Golgi body (packing and shipping plants)
Synthesizes proteins and lipids and packages them for delivery outside the cell
Mitochondrion (power plants)
Site of cellular respiration; provides most of the cell’s ATP
Lysosome (garbage disposals)
Engulfs, destroys, and digests pathogens and cellular debris
Nucleus (control center)
Directs most metabolic activities, including growth and reproduction; contains DNA and RNA
