cell (plasma) membrane
structure: membrane composed of a double layer of phospholipids in which proteins are embedded. functions: gives form to cell and controls passage of materials in and out of cell
structure: fluid, jellylike substance between the cell membrane and the nucleus in which organelles are suspended. functions: serves as matrix substance in which chemicals reactions occur
endoplasmic reticulum
structure: system of interconnected membrane-forming canals and tubules function: provides supporting framework within cytoplasm; transports materials and provides attachment for ribosomes.
structure: granular particles composed of protein and RNA function: synthesize proteins
golgi complex
structure:cluster of flattened membranous sacs function:synthesizes carbohydrates and package molecules and break down hydrogen peroxide
structure:nonmembranous mass of two rodlike centrioles function: helps organize spindle fibers and distribute chromosomes during mitosis of a cell cycle
structure:membranous sac function: store and release various substances within the cytoplasm
fibrils and microtubules
structure: thin, hollow tubes function: support cytoplasm and transport materials within the cytoplasm
cilia and flagella
structure: minute cytoplasmic projections that extend from the cell surface function: move particles along cell surface or move the cell
nuclear membrane (envelope)
structure: double-walled membrane composed of protein and lipid molecules that surrounds the nucleus function: supports nucleus and controls passage of materials between nucleus and cytoplasm
structure: dense nonmembranous mass composed of protein and RNA molecules function: forms ribosomes
structure: fibrous strands composed of protein and DNA molecules function: contains genetic code that determines which proteins (especially enzymes) will be manufactured by the cell.
structure: double-walled membranous sacs with folded inner partitions function: release energy from food molecules and transform energy into unusable ATP
structure: single-walled membranous sacs function: digest foreign molecules and worn and damaged cells
structure: spherical membranous vesicles function: contains enzymes that detoxify harmful molecules and break down hydrogen peroxide.
