2. Looking Inside Eukaryotic Cells

3. PARTS OF A CELL “PARTS OF A CITY”

4. TWO TYPES OF CELLS 1) PROKARYOTE Without a nucleus = Bacteria

5. TWO TYPES OF CELLS 2) EUKARYOTE With a nucleus = Animal & Plant

6. STRUCTURE OF A TYPICAL PLANT CELL

7. PLANT CELL

8. CELL WALL “SHORELINE & BOUNDARY” A RIGID LAYER THAT PROVIDES SHAPE AND SUPPORT TO A PLANT CELL

9. STRUCTURE OF A TYPICAL ANIMAL CELL

10. ANIMAL CELL

11. CELL MEMBRANE “OUTER GATE” CONTROLS WHICH SUBSTANCES CAN ENTER OR LEAVE THE CELL

12. OUTER GATE

13. NUCLEUS “BRAIN OR COMPUTER” THE CONTROL CENTER OF A CELL THAT DIRECTS THE CELL’S ACTIVITIES; CONTAINS GENETIC MATERIAL CALLED CHROMOSOMES MADE OF DNA

14. BRAIN = COMPUTER

15. CYTOPLASM “ATMOSPHERE” THE VISCOUS GEL-LIKE MATERIAL INSIDE A CELL; CONTAINS ORGANELLES “ENVIRONMENT”

16. ENVIRONMENT

17. ATMOSPHERE

18. MITOCHONDRIA “POWERHOUSE” ROD-SHAPED ORGANELLE WHERE ENERGY FOR CELLULAR FUNCTIONS IS PRODUCED

19. MITOCHONDRIA = POWER PLANT

20. POWERHOUSE

21. ENDOPLASMIC RETICULUM ( E R ) “HIGHWAY” MAZE OF PASSAGEWAYS IN WHICH MATERIALS ARE CARRIED FROM ONE PART OF THE CELL TO ANOTHER

22. HIGHWAY = TRANSPORTATION

23. RIBOSOME “FACTORY & PRODUCERS” A TINY STRUCTURE IN THE CYTOPLASM OF A CELL WHERE PROTEINS ARE MADE

24. RIBOSOME = FACTORY

25. GOLGI BODY “POST OFFICE” PACKAGES & DISTRIBUTES PROTEINS IN LITTLE BUBBLES TO OTHER PARTS OF THE CELL

26. GOLGI BODY = POST OFFICE

27. CHLOROPLASTS “FARM & SITE OF PHOTOSYNTHESIS” CAPTURE ENERGY FROM SUNLIGHT AND USES IT TO PRODUCE FOOD FOR PLANT CELLS ; CONTAIN CHLOROPHYLL

28. VACUOLE “GROCERY STORE” BUBBLE-LIKE ORGANELLE THAT STORES FOOD, WATER, OR WASTE

29. LYSOSOME “RECYCLERS & DIGESTION CENTER” A SACLIKE ORGANELLE IN ANIMAL CELLS THAT CONTAINS CHEMICALS THAT BREAKDOWN FOOD OR WASTE MATERIALS

30. DIGESTION CENTER Lysosomes are relatively large vesicles formed by the Golgi. They contain hydrolytic enzymes that could destroy the cell. Lysosome contents function in the extracellular breakdown of materials.
