External boundary of cell; regulates flow of materials into & out of the cell; site of cell signaling Plasma Membrane
Contains digestive enzymes of many varieties; "suicide sac" of the cell Lysosome
Scattered throughout the cell; major site of ATP synthesis Mitochondria
Slender extensions of the plasma membrane that increase its surface area Microvilli
Stored glycogen granules, crystals, pigments & so on Inclusions
Membranous system consisting of flattened sacs & vesicles; packages proteins for export Golgi apparatus
Control center of the cell; necessary for cell division Nucleus
Two rod-shaped bodies near the nucleus; direct formation of the mitotic spindle Centrioles
Contractile elements of the cytoskeleton Microfilaments
Membranous system; involved in intracellular transport of proteins & synthesis of membrane lipids Rough ER or endoplasmic reticulum
