FUNCTIONS

CELL MEMBRANE SUPPORT AND PROTECT CELLS SELECTIVELY PERMEABLE – ALLOWS SOME SUBSTANCES TO ENTER AND KEEPS OTHER SUBSTANCES OUT THIN FLEXIBLE BARRIER AROUND THE CELL ALL ORGANISMS HAVE A CELL MEMBRANE

CELL WALL SUPPORT AND PROTECT CELLS OUTSIDE OF THE CELL MEMBRANE PLANT, FUNGI, PROTIST AND BACTERIA HAVE CELL WALLS ANIMAL CELLS DO NOT HAVE CELL WALLS

NUCLEUS THE CONTROL CENTER OF THE CELL CONTAINS THE CHROMOSOMES – THREADLIKE STRUCTURES THAT CONTAIN DNA(THE GENETIC INFORMATION)

CYTOPLASM COMPOSED OF EVERYTHING INSIDE OF THE CELL EXCEPT THE GENETIC MATERIAL FLUID PORTION IS THE CYTOSOL

NUCLEOLUS MAKES THE RIBOSOMES INSIDE OF THE UNDIVIDING NUCLEUS

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

CYTOSKELETON HELPS THE CELL MAINTAIN ITS SHAPE MICROTUBULES – 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 MICROTUBULES FORM DURING CELL DIVISION IN ANIMAL CELLS HELP ANCHOR THE SPINDLE FIBERS DURING CELL DIVISION

RIBOSOMES SITE OF PROTEIN SYNTHESIS FREE FLOATING IN CYTOPLASM OR ATTACHED TO ENDOPLASMIC RETICULUM

ENDOPLASMIC RETICULUM TWO TYPES: ROUGH E R – COVERED WITH RIBOSOMES SMOOTH E R- NO RIBOSOMES ON IT

ROUGH E R FUNCTIONS MAKES PROTEINS TO BE USED IN MEMBRANES MAKES PROTEINS TO BE USED IN CERTAIN ORGANELLES MAKES PROTEINS THAT ARE EXPORTED OUT OF THE CELL MEMBRANE REPAIR FACTORY-REPAIRS DAMAGED OR WORN OUT PARTS

SMOOTH E R FUNCTIONS MAKES LIPIDS (FATS, OILS, WAXES, STEROIDS) DETOXIFICATION OF DRUGS AND POISONS METABOLISM OF CARBOHYDRATES TRIGGERS CONTRACTION OF MUSCLE CELLS

GOLGI APPARATUS ATTACH CARBOHYDRATES AND LIPIDS TO PROTEINS SENDS CARBS AND LIPIDS TO THEIR FINAL DESTINATION MANUFACTURES CERTAIN POLYSACCHARIDES FLATTENED STACK OF MEMBRANES

LYSOSOMES CONTAINS ENZYMES THAT BREAK DOWN DIFFERENT SUBSTANCES BREAK DOWN LIPIDS, CARBOHYDRATES AND PROTEIN FROM FOOD BREAK DOWN OLD WORN-OUT ORGANELLES REMOVE “GARBAGE” FROM THE CELL

VACUOLES STORES AND TRANSPORTS WATER, SALTS, PROTEINS AND CARBOHYDRATES

VESICLES STORAGE AND TRANSPORT OF NUTRIENTS, ENZYMES AND PROTEINS REMOVAL OF WASTE PRODUCTS FROM THE CELL

MITOCHONDRIA THE POWERHOUSE OF THE CELL RELEASE ENERGY FROM STORED FOOD MOLECULES SITE OF CELLULAR RESPIRATION

CHLOROPLASTS USE THE ENERGY FROM SUNLIGHT TO MAKE ENERGY RICH FOOD COMPOUNDS THE SITE OF PHOTOSYNTHESIS
