Chloroplast and mitochondria

  1. 1. Chloroplasts & Mitochondria * Compare and contrast the functions of chloroplasts and mitochondrion <ul><li>The cellular machinery requires a coninuous energy supply to do all the work of life. </li></ul><ul><li>The two types of cellular power stations are organelles called chloroplasts & mitochondria . </li></ul><ul><li>One harnesses light energy from the sun, and the other &quot;unpacks&quot; this captured energy into smaller packets that are useful for powering cellular work. </li></ul>
  2. 2. <ul><li>The cellular machinery requires a continuous energy supply to do all the work of life. </li></ul>
  3. 3. <ul><li>The two types of cellular power stations are organelles called chloroplasts & mitochondria . </li></ul>
  4. 4. <ul><li>One harnesses light energy from the sun, and the other &quot;unpacks&quot; this captured energy into smaller packets that are useful for powering cellular work. </li></ul>
  5. 5. Cellular Respiration <ul><li>The process by which cells make ATP </li></ul>
  6. 6. Photosynthesis <ul><li>Process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and C 6 H 12 O 6 (glucose or sugar) . </li></ul>
  7. 7. Chloroplasts <ul><li>Plants and algae (plant-like protists) harness light energy through photosynthesis. </li></ul><ul><li>Found only in Eukarya autotrophs/producers </li></ul>the sun sugar
  8. 8. Chloroplasts <ul><li>Light Energy + water & carbon dioxide Sugars (which are used as chemical energy) & oxygen </li></ul><ul><li>Found only in Eukarya autotrophs or producers </li></ul>
  9. 9. <ul><li>Two membranes </li></ul><ul><li>Fluid filled space ( stroma ) </li></ul><ul><li>Disk shaped structures ( thylakoids ) </li></ul><ul><li>Stack of disks ( granum ) </li></ul><ul><li>Multiple stacks ( grana ) </li></ul>
  10. 10. Chloroplasts Netrium digitus A freshwater protist
  11. 11. Mitochondria singular: mitochondrion <ul><li>In all eukaryotic cells, mitochondria perform cellular respiration </li></ul>Sugar ATP = energy
  12. 12. Mitochondria singular: mitochondrion <ul><li>Sugar ATP </li></ul><ul><li>(adenosine triphosphate) </li></ul>
  13. 13. ATP <ul><li>In all eukaryotic cells, mitochondria perform cellular respiration </li></ul><ul><li>Sugar ATP (adenosine triphosphate) </li></ul><ul><li>Adenine (blue part) </li></ul><ul><li>Ribose (red part) </li></ul><ul><li>3 phosphates (green part) </li></ul>
  14. 14. Mitochondria singular: mitochondrion <ul><li>Double membrane </li></ul><ul><li>Inner membrane has many folds . </li></ul>
  15. 15. Mitochondria singular: mitochondrion <ul><li>Inner membrane also has many enzymes for cellular respiration. </li></ul><ul><li>MATRIX-Inner fluid filled space </li></ul>
  16. 16. Plant cells have both mitochondria and chloroplasts
