5th Grade Ch. 2 Lesson 1 What is inside a cell?

  1. 1. Ch. 2 Lesson 1 What is Inside a Cell?
  2. 2. cell <ul><li>basic building block that makes up all living things </li></ul>
  3. 3. cell functions take in food get rid of wastes grow get energy respond to environ- ment
  4. 4. nucleus cytoplasm cell wall chloroplasts cell membrane cell membrane nucleus cytoplasm vacuole vacuole mitochondria mitochondria
  5. 5. cell parts functions <ul><li>cell membrane </li></ul><ul><li>surrounds cell-holds it together </li></ul><ul><li>allows materials to pass in & out of cell </li></ul><ul><li>nucleus </li></ul><ul><li>contains chromosomes (DNA) </li></ul>
  6. 6. cell parts functions <ul><li>cytoplasm </li></ul><ul><li>between cell membrane & </li></ul><ul><li>nucleus </li></ul><ul><li>mitochondria </li></ul><ul><li>produce energy by cellular </li></ul><ul><li>respiration </li></ul>
  7. 7. cell parts functions <ul><li>vacuole </li></ul><ul><li>stores H 2 0 & breaks </li></ul><ul><li>down materials </li></ul><ul><li>cell wall </li></ul><ul><li>(only in plants) </li></ul><ul><li>outside cell membrane </li></ul><ul><li>gives extra support & </li></ul><ul><li>protection </li></ul><ul><li>chloroplasts </li></ul><ul><li>(only in </li></ul><ul><li>plants) </li></ul><ul><li>uses Sun’s energy to </li></ul><ul><li>make food (sugar) & </li></ul><ul><li>oxygen </li></ul>
  8. 8. <ul><li>The cell walls of these onion skin cells can be seen in the photograph below. </li></ul>
  9. 9. An Elodea leaf magnified 400X. The numerous green structures are chloroplasts.
  10. 10. PICTURE OF A REAL CELL MEMBRANE <ul><li>It has been magnified so that we can see it! </li></ul>
  11. 11. The nuclei can be seen in the photograph of human cheek cells below.
  12. 13. The Parts of a Cell
  13. 14. The Size of Cells <ul><li>How Big is a Cell? </li></ul><ul><li>Cells have a limit to how big or small they can be. </li></ul>
  14. 16. cell membrane <ul><li>surrounds cell-holds it together </li></ul><ul><li>allows materials to pass in & out of cell </li></ul>
  15. 17. cell <ul><li>basic building block that makes up all living things </li></ul>
  16. 18. cytoplasm <ul><li>between cell membrane & nucleus </li></ul>
  17. 19. chloroplast <ul><li>found in plant cells </li></ul><ul><li>uses Sun’s energy to </li></ul><ul><li>make food (sugar) & </li></ul><ul><li>oxygen </li></ul>
  18. 20. cell wall <ul><li>found in plants outside the cell membrane </li></ul><ul><li>gives extra support & </li></ul><ul><li>protection </li></ul>
  19. 21. vacuole <ul><li>stores H 2 0 & breaks down materials </li></ul>
  20. 22. mitochondria <ul><li>produce energy by cellular respiration </li></ul>
  21. 23. cytoplasm
  22. 24. cell membrane
  23. 25. mitochondria
  24. 26. chloroplast
  25. 27. cell wall
  26. 28. vacuole
  27. 29. Cell parts in plants and animals
  28. 30. The skin on the Barbie doll is like the cell membrane of a cell because both are outside surfaces, and allow substances to pass in and out of the cell. Cell Analogy Project
  29. 31. Edible Animal Cell <ul><li>cell membrane = plastic bag </li></ul><ul><li>Jello = cytoplasm </li></ul><ul><li>2 raisins = mitochondria </li></ul><ul><li>1 pear = nucleus </li></ul><ul><li>2 peaches = vacuoles </li></ul>
