1. 1 Cell Structure & Function

2. 2 KINDS OF ORGANISMS _____________________ Can make own food Example: __________________ AUTOTROPHS Green Plants

3. 2 KINDS OF ORGANISMS _____________________ Can’t make food Get energy by eating other organisms Examples: ________________ HETEROTROPHS Animals & YOU

4. 2 KINDS OF CELLS __________________ “No nucleus or organelles” EXAMPLE: Bacteria PROKARYOTES

5. 2 KINDS OF CELLS _________________ “Nucleus with organelles” EXAMPLE: Animal & plant cells EUKARYOTES

6. WHICH IS BIGGER? Bacteria Animal Cell Plant cell Small SmallerSmallest

7. Cell size

8. CELL (Plasma) MEMBRANE Holds contents inside

9. CELL MEMBRANE Controls what enters and leaves Semi-permeable

10. SELECTIVELY PERMEABLE

11. CELL MEMBRANES are mainly PHOSPHOLIPIDS POLAR HEAD- “hydrophillic” TAILS- “hydrophobic”

12. _______________ = SURFACE protein PERIPHERAL MEMBRANE PROTEINS

13. ______________ INTEGRAL Tunnel through membrane Image modified from: http://bio.winona.msus.edu/berg/ILLUST/Bil&mem3.jpg

14. FLUID MOSAIC MODEL Image from: http://bio.winona.msus.edu/berg/ILLUST/memb-mod.jpg

15. CYTOPLASM = cytosol + organelles _________________ structures with special function ___________ gel-like goo CYTOSOL ORGANELLES

16. CYTOSKELETON Gives cell shape & support

17. NUCLEUS Control center

18. NUCLEUS Contains genetic material

19. CHROMATIN (DNA & proteins)

20. NUCLEOLUS Dark spot on nucleus = (makes ribosomes)

21. MITOCHONDRION Powerplant of cell Burns glucose to release ATP

22. MITOCHONDRIA inner membrane called CRISTAE Increases surface area for more chemical reactions

23. RIBOSOMES Make proteins

24. ROUGH ER Has RIBOSOMES Transports molecules to other parts of cell

25. SMOOTH ER Moves material for export from cell

26. GOLGI BODY Packages molecules for transport out of cell

27. VACUOLES Storage for water and waste

28. LYSOSOMES Digest unwanted cells and cell parts

29. CILIA & FLAGELLA -Help in cell movement

30. CILIA Many short FLAGELLA One Long

31. CENTRIOLES Separate chromosomes during cell division

32. CENTRIOLES

33. CELL WALL Supports and protects cell

34. PLANT CELLS Cell wall Chloroplasts Bigger vacuoles No centrioles

35. CHLOROPLASTS Use light and CO2 to make glucose

36. NO CENTRIOLES in Plan ts

37. CELL THEORY 2. Cells are the BASIC UNIT of structure and function in an organism 1. ALL living things are made of CELLS 3. All cells come from the reproduction of existing cells.

38. 38 Number of Cells Organisms may be: Unicellular –one cell Multicellular- many cells

39. SIZE CELLS  TISSUES Similar cells working together

40. TISSUES  ORGANS Image from: http://www.emc.maricopa.edu/faculty/farabee/BIOBK/BioBookAnimalTS.html

41. ORGANS  ORGAN SYSTEMS

42. ORGAN SYSTEMS  ORGANISM
