Cell parts

  1. 1. THE CELL<br />
  2. 2. Contributors to Knowledge of Cell<br />Robert Hooke (1665)- Discovered the cell<br />Anton van Leeuwenhoek (mid-1600s)- viewed living organisms under microscope<br />Matthias Schleiden (1838)- plants are made of cells<br />Theodor Schwann (1839)- animals are made of cells<br />Rudolf Virchow (1855)- new cells are produced only from division of old cells<br />
  3. 3. The Cell Theory<br />The discoveries of Hooke, Schleiden, Schwann, and Virchow are summarized in the cell theory, which states that:<br />All living things are composed of cells.<br />Cells are the basic units of structure and function in living things.<br />New cells are produced from existing cells.<br />
  4. 4. Types of Cells<br />
  5. 5. Types of Cells<br />
  6. 6. Cell Parts<br />Descriptions<br />Functions<br />Location<br />Cell type<br />
  7. 7. Cytoplasm<br />Jelly -like substance<br />Made mostly of water<br />Holds all organelles<br />Between the cell membrane and nuclear membrane<br />Both plant and animal cell<br />
  8. 8. Cell(plasma) membrane<br />Outer portion of the cell<br />Boundaries of inside organelles<br />Controls movement inside and outside of the cell<br />Both plant and animal cells<br />
  9. 9. Animal Cell<br />
  10. 10. Nucleus<br /><ul><li>Round dark organelle in cytoplasm
  11. 11. Control center for cell
  12. 12. Contains DNA/chromatin and nucleolus
  13. 13. Both plant and animal cells</li></li></ul><li>Nuclear Membrane (envelope)<br /><ul><li>Membrane that surrounds nucleus
  14. 14. Controls movement of materials in and out of nucleus
  15. 15. Both plant and animal cells</li></li></ul><li>Nucleolus<br />Located in nucleus, dark spots<br />Made of chromatin<br />Makes ribosomes<br />Both plant and animal cells<br />
  16. 16.
  17. 17. Microtubules(cytoskeleton)<br />Microtubules (cytoskeleton)<br />Thin protein strands, but thicker than microfilaments<br />Provide support for cell<br />Aide in movement<br />Both plant and animal<br />Found in cytoplasm<br />
  18. 18. Microfilaments(cytoskeleton)<br />Microtubules (cytoskeleton)<br />Thin protein strands, but thinner than microtubules<br />Provide support for cell<br />Aide in movement<br />Both plant and animal<br />Found in cytoplasm<br />
  19. 19.
  20. 20. Centrioles<br />Cylinder shaped, each cell has a pairHelp cell divide<br />ONLY in animal cells<br />Found in cytoplasm<br />
  21. 21.
  22. 22. Vacuole<br />Sac shaped vesicle<br />Used for storage of food, water, and wastes<br />Much larger in plant cells<br />Both plant and animal cells<br />Located in cytoplasm<br />
  23. 23.
  24. 24. Chloroplast<br />Located in the cytoplasm<br />Green from chlorophyll<br />Used in photosynthesis to make food<br />Only in plants<br />
  25. 25.
  26. 26. Ribosomes<br />Small circles or dots located in cytoplasm or on the Endoplasmic Reticulum<br />Made by the nucleolus<br />Make protein<br />Both plant and animal cells<br />
  27. 27.
  28. 28. Cell Wall<br />Layer outside cell membrane in plant cells<br />Give cell support/shape <br />Made of cellulose<br />Only in plant cells<br />
  29. 29.
  30. 30. Golgi Apparatus(complex, bodies)<br />Located in cytoplasm<br />Looks like fruit rollups<br />Packages materials in vessicles and ships them to the needed locations<br />Adapts proteins made by ribosomes<br />Both plant and animal cells<br />
  31. 31.
  32. 32. Mitochondria<br />Double membrane organelle<br />Powerhouse of the cell, releases the cell’s energy from stored food<br />Contains its own DNA <br />If cell requires more energy (muscle) it will have more mitochondria<br />Both plant and animal cells<br />
  33. 33.
  34. 34. Endoplasmic Reticulum<br />Network of tubes connecting cell membrane to other organelles<br />SER makes lipids<br />RER makes proteins<br />Transports materials throughout cell<br />Can be rough (with ribosomes) or smooth (without ribosomes)<br />Both plant and animal cells<br />
  35. 35.
  36. 36. Chromosomes/Chromatin<br />Thread like genetic material<br />Located in nucleus<br />Contains all the information for the cells’ activities<br />Both plant and animal cells<br />
  37. 37.
  38. 38.
  39. 39. Chromatids<br />Two strands make up a chromosome<br />Located in the nucleus except during cell division where they are pulled apart by the centrioles<br />Used in the duplication of the cell<br />Both plant and animal cells<br />
  40. 40.
  41. 41. Cilia<br />Hair like structures attached to the cell membrane<br />Responsible for movement <br />In animal cells<br />
  42. 42.
  43. 43. Flagellum<br />Hair like structure attached to the cell membrane<br />Responsible for movement<br />In animal cells<br />
  44. 44.
  45. 45. Lysosomes<br />Sac like structure that contains chemical that help in digestion and breaking down materials<br />Located in the cytoplasm <br />Only in animal cells<br />
