LOOKING INSIDE CELLS CH 3 SEC 2

PURPOSE § - STUDENTS SHOULD KNOW THE CHARACTERISTICS OF PLANT AND ANIMALS CELL AND THEIR DIFFERENCES § STUDENTS SHOULD BE ABLE TO NAME THE ORGANELLES AND THEIR FUNCTIONS

WHAT IS INSIDE A CELL? § KEY- THERE ARE EVEN SMALLER STRUCTURES INSIDE CELLS CALLED ORGANELLES § ORGANELLES- CARRY OUT SPECIFIC FUNCTIONS WITHIN THE CELL JUST LIKE OUR ORGANS- HEART, BRAIN, ETC § http: //www. brainpop. com/science/cellularlif eandgenetics/cells/

ANIMAL CELL DEFINE 2

CELL ORGANELLE TOUR § CELL WALL- IS A RIGID LAYER OF NON-LIVING MATERIAL THAT SURROUNDS THE CELLS OF PLANTS § KEY- THE CELL WALL HELPS PROTECT AND SUPPORT THE CELL.

PLANT CELL DEFINE 2

CELL MEMBRANE § KEY- ALL CELLS HAVE CELL MEMBRANES IN THEIR OUTER LAYERS § KEY- THE CELL MEMBRANE CONTROLS WHAT SUBSTANCES COME INTO AND OUT OF A CELL § KEY- FOR A CELL TO SURVIVE THE CELL MEMBRANE ALLOWS MATERIALS LIKE FOOD AND WATER PASS THROUGH THE MEMBRANE AND WASTE TO EXIT. § EX- LIKE THE SCHOOL FENCE

CELL MEMBRANE SKETCH

NUCLEUS § NUCLEUS- ACTS AS THE CONTROL CENTER OF THE CELL § KEY- THE NUCLEUS DIRECTS ALL OF THE CELLS ACTIVITIES § EX- YOUR BRAIN § KEY- THE NUCLEUS CONTAINS THE CELLS GENETIC MATERIAL

NUCLEUS SKETCH

ORGANELLES IN THE CYTOPLASM § CYTOPLASM- IS THE REGION BETWEEN THE CELL MEMBRANE AND THE NUCLEUS § KEY- IT IS A CLEAR, THICK, GEL-LIKE FLUID. SKETCH

CYTOPLASM § KEY- IN THE CYTOPLASM ARE MANY ORGANELLES. EACH OF THESE CARRY OUT A SPECIFIC FUNCTION IN THE CELL.

ORGANELLES list and number in abc order

ORGANELLES CONT’D § GOLGI BODIES- CELLS MAIL ROOM. THEY PACKAGE AND DISTRIBUTE MATERIALS THROUGHOUT THE CELL AND THEY RELEASE WASTE. § SKETCH

KEY- PLANT CELLS ONLY § CHLOROPLAST- FOUND IN PLANT CELLS ONLY. CAPTURE ENERGY FROM SUNLIGHT AND MAKE FOOD § EXAMPLE § GREEN LEAVES

§ VACUOLES- STORAGE AREA FOR CELLS. THEY STORE FOOD AND OTHER MATERIALS NEEDED BY THE CELL. § KEY- MOST PLANT CELLS HAVE ONE LARGE VACUOLE FOR WATER. § SKETCH

ORGANELLES CONT’D § LYSOSOMES- ARE SMALL ROUND STRUCTURES CONTAINING CHEMICALS THAT BREAK DOWN CERTAIN MATERIALS INTO SMALLER ONES. CELLS CLEANUP CREW. § SKETCH
