  1. LOOKING INSIDE CELLS CH 3 SEC 2

  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

  3. 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/cellularlifeandgenetics/cells/

  4. ANIMAL CELL DEFINE 2

  5. 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.

  6. PLANT CELL DEFINE 2

  7. 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

  8. CELL MEMBRANE SKETCH

  9. 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

  10. NUCLEUS SKETCH

  11. 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

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

  13. ORGANELLES list and number in abc order

  14. ORGANELLES AND THEIR FUNCTION • MITOCHONDRIA- ROD SHAPED STRUCTURES THAT ARE KNOWN AS THE “POWERHOUSES'’ OF THE CELLS. • KEY- RELEASE THE • CELLS ENERGY • SKETCH

  15. ENDOPLASMIC RETICULUM- MAZE OF PASSAGEWAYS THAT HELP FORM PROTEINS AND CARRY MATERIALS THROUGHOUT THE CELL • SKETCH

  16. RIBOSOMES- PRODUCE PROTEINS ON THE WALLS OF THE E.R. AND IN THE CYTOPLASM • SKETCH

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

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

  19. 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

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

  21. CELL DIVERSITY • KEY-CELLS COME IN MANY SHAPES AND SIZES DEPENDENT ON THEIR FUNCTION. • http://www.brainpop.com/science/cellularlifeandgenetics/cellstructures/ • http://www.teachertube.com/viewVideo.php?video_id=248477

  22. REVIEW ANSWER QUESTIONS P.95
