Cell Structures and Functions

Structure Functions
CELL WALL *ANIMAL CELLS DON'T HAVE ONE
*PLANTS: MADE OF CELLULOSE
*GIVES STRENGTH STRUCTURE AND RIGIDITY TO PLANT THRU TURGOR PRESSURE
CELL MEMBRANE *OUTSIDE COVERING
*DETERMINES WHAT GOES IN/OUT OF CELL
*FLEXIBLE BUT SUPPORTS CELLS
VACUOLE *STORAGE UNIT IN CELLS THAT HOLD WATER
*LARGE IN PLANTS,SMALL IN ANIMAL CELLS
NUCLEUS *CONTROL CENTER OF CELL
*HOUSES DNA
*CONTROLS CELL GROWTH AND MAKES RIBSOME
LYSOSOME `*CONTAINS DIGESTIVE ENZYMES TO BREAK THINGS DOWN IN A CELL
CYTOPLASM *GELATINOUS, SEMI-TRANSPARENT FLUID THAT FILLS THE CELLS
*ORGANELLES ARE SUSPENDED IN CYTOPLASM
ROUGH ENDOPLASMIC RETICULUM *COVERED IN RIBOSOMES, STORES PROTEINS
SMOOTH ENDOPLASMIC RETICULUM *(NO RIBOSOMES) TRANSPORTS CELLS PRODUCTS
RIBSOME *SITE OF PROTEIN SYNTHESIS
GOLGI BODY *PACKAGES CELL PRODUCTS FOR TRANSPORT(LIKE UPS)
CHLOROPLAST *SITE OF PHOTOSYNTHESIS: CAPTURES RADIANT ENERGY AND CONVERTS INTO CHEMICAL ENERGY (C6H12O6)
*HAS CHLOROPHYLL- GREEN PIGMENT THAT ABSORBS LIGHT
MITOCHONDRIA *"POWER HOUSE OF THE CELLS"
*PRODUCES ENERGY (BREAKS DOWN GLUCOSE)
* C6H12O6+ O2 -> CO2 + H2O + ENERGY
