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

4. ANIMAL CELL

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

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

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

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.

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

13. ORGANELLES

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

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

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

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

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

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

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

21. CELL DIVERSITY
KEY-CELLS COME IN MANY SHAPES AND SIZES DEPENDENT ON THEIR FUNCTION.
