Transcript

  • 1. Organelles from Cells Group 3
  • 2. PROKARYOTIC ORGANELLES
  • 3. Plasma (cell) Membrane <ul><li>Encloses cytoplasm of cell </li></ul><ul><li>Basically controls what can go and out of the cell (ex. Functions like a bouncer at a club). </li></ul><ul><li>Uses active and passive transport </li></ul>
  • 4. Nucleoid Region <ul><li>Area where DNA is located </li></ul><ul><li>Has nuclear material without actually having a nuclear membrane </li></ul><ul><li>Prokaryotic genome is a circular double-stranded DNA </li></ul>
  • 5. Ribosomes <ul><li>Assembles proteins with information from DNA </li></ul>
  • 6. Cell Wall <ul><li>Rigid outer layer that surrounds the cell membrane </li></ul><ul><li>It protects the cell and maintains its shape </li></ul>
  • 7. Flagella <ul><li>Longer projections that help with locomotion of the cell </li></ul>
  • 8. Chloroplast <ul><li>A plastid that contains chlorophyll </li></ul><ul><li>Chlorophyll is what makes the leaves and plants green </li></ul>
  • 9. Pili and Fimbriae <ul><li>Numerous short projections that help with the attachment of support </li></ul>
  • 10. Capsule and Cytoplasm <ul><li>The capsule is the sticky outer layer over the cell wall; it keeps the cell together </li></ul><ul><li>The cytoplasm is just the cytosol including all the organelles except the nucleus </li></ul>
  • 11. EUKARYOTIC ORGANELLES
  • 12. Mitochondria <ul><li>Its primary function is to generate energy in the form of ATP </li></ul><ul><li>It also stores calcium for cell signaling activities; generates heat; mediates cell growth and death </li></ul>
  • 13. Nucleus, Nucleolus and Nuclear Envelope <ul><li>The nucleus is the cell’s genetic control center-> consists of a double membrane, nuclear envelope, nuclear pores, chromatin, nucleolus, and nucleoplasm </li></ul>
  • 14. Chromatin <ul><li>It’s a stainable substance of the cell nucleus consisting of DNA, RNA, and various proteins that form chromosomes during cell division </li></ul>
  • 15. Endoplasmic Reticulum-> Rough & Smooth <ul><li>Single continuous membrane with nuclear envelope -> serves as a highway for the cell </li></ul><ul><li>Rough ER: covered with ribosomes, major site of protein synthesis </li></ul><ul><li>Smooth ER: lacks ribosomes; it transports, synthesizes lypids, detoxifies, and stores calcium ions </li></ul>
  • 16. Golgi Apparatus <ul><li>Handles export and import of material for the cell </li></ul><ul><li>It stores, packages, sorts and modifies proteins before they are exported </li></ul><ul><li>Considered the UPS of the cell </li></ul>
  • 17. Centrioles <ul><li>Cellular structure that is composed of nine triplet microtubles and forms the asters during mitosis </li></ul><ul><li>Divides in a perpendicular from during mitosis </li></ul>
  • 18. Microtubles <ul><li>They are conveyer belts inside the cells </li></ul><ul><li>They move vesicles, granules, organelles like mitochondria, and chromosomes through a special attachment of proteins </li></ul>
  • 19. Vacuoles <ul><li>Very large in size </li></ul><ul><li>Work with lysosomes for digestion </li></ul><ul><li>Stores food and water as well as wastes and excess water </li></ul>
  • 20. Microfilaments <ul><li>It gives shape to the cell and are involved in the constriction of cytoplasm during divisions in animal cells </li></ul>
  • 21. Peroxisome <ul><li>Breakdown lipids </li></ul><ul><li>Detoxifies alcohols and hydrogen peroxide </li></ul>
  • 22. Lysosome <ul><li>Contain digestive enzymes </li></ul><ul><li>Breakdown cell’s food and wastes </li></ul>
