Cell OrganellesFUNCTIONS

CELL MEMBRANESUPPORT AND PROTECT CELLSSELECTIVELY PERMEABLE –

ALLOWS SOME SUBSTANCES TO ENTER AND KEEPS OTHER SUBSTANCES OUT

THIN FLEXIBLE BARRIER AROUND THE CELL

ALL ORGANISMS HAVE A CELL MEMBRANE

CELL WALLSUPPORT AND PROTECT CELLS

OUTSIDE OF THE CELL MEMBRANE

PLANT, FUNGI, PROTIST AND BACTERIA HAVE CELL WALLS

ANIMAL CELLS DO NOT HAVE CELL WALLS

NUCLEUSTHE CONTROL CENTER OF THE CELL

CONTAINS THE CHROMOSOMES – THREADLIKE STRUCTURES THAT CONTAIN DNA(THE GENETIC INFORMATION)

CYTOPLASMCOMPOSED OF EVERYTHING INSIDE OF THE CELL EXCEPT THE GENETIC MATERIAL

FLUID PORTION IS THE CYTOSOL

NUCLEOLUSMAKES THE RIBOSOMES

INSIDE OF THE UNDIVIDING NUCLEUS

NUCLEAR ENVELOPE (MEMBRANE)ALLOW MATERIALS TO MOVE INTO AND OUT OF THE NUCLEUS

SURROUNDS THE NUCLEUS

CYTOSKELETONHELPS THE CELL MAINTAIN ITS

SHAPEMICROTUBULES – MAINTAIN

CELL SHAPE & SERVE AS TRACKS ALONG WHICH ORGANELLES MOVE (TUBE SHAPE)

MICROFILAMENTS – MOVEMENT AND SUPPORT OF THE CELL (THIN FILAMENTS)

CYTOSKELETON – CENTRIOLES

PART OF MICROTUBULESFORM DURING CELL DIVISION IN ANIMAL CELLS

HELP ANCHOR THE SPINDLE FIBERS DURING CELL DIVISION

RIBOSOMESSITE OF PROTEIN SYNTHESIS

FREE FLOATING IN CYTOPLASM OR

ATTACHED TO ENDOPLASMIC RETICULUM

ENDOPLASMIC RETICULUMTWO TYPES:

ROUGH E R – COVERED WITH RIBOSOMES

SMOOTH E R- NO RIBOSOMES ON IT

ROUGH E R FUNCTIONSMAKES PROTEINS TO BE USED IN

MEMBRANESMAKES PROTEINS TO BE USED IN

CERTAIN ORGANELLESMAKES PROTEINS THAT ARE

EXPORTED OUT OF THE CELLMEMBRANE REPAIR FACTORY-

REPAIRS DAMAGED OR WORN OUT PARTS

SMOOTH E R FUNCTIONSMAKES LIPIDS (FATS, OILS, WAXES, STEROIDS)

DETOXIFICATION OF DRUGS AND POISONS

METABOLISM OF CARBOHYDRATES

TRIGGERS CONTRACTION OF MUSCLE CELLS

GOLGI APPARATUSATTACH CARBOHYDRATES AND

LIPIDS TO PROTEINSSENDS CARBS AND LIPIDS TO

THEIR FINAL DESTINATIONMANUFACTURES CERTAIN

POLYSACCHARIDESFLATTENED STACK OF

MEMBRANES

LYSOSOMESCONTAINS ENZYMES THAT BREAK

DOWN DIFFERENT SUBSTANCESBREAK DOWN LIPIDS,

CARBOHYDRATES AND PROTEIN FROM FOOD

BREAK DOWN OLD WORN-OUT ORGANELLES

REMOVE “GARBAGE” FROM THE CELL

VACUOLESSTORES AND TRANSPORTS WATER, SALTS, PROTEINS AND CARBOHYDRATES

VESICLESSTORAGE AND TRANSPORT OF NUTRIENTS, ENZYMES AND PROTEINS

REMOVAL OF WASTE PRODUCTS FROM THE CELL

MITOCHONDRIATHE POWERHOUSE OF THE CELL

RELEASE ENERGY FROM STORED FOOD MOLECULES
