Transcript of "Cell organelles"

  1. 1. Cell Organelles <ul><li>By: </li></ul><ul><li>Karyn </li></ul><ul><li>Ferguson </li></ul>
  2. 2. CYTOPLASM <ul><li>Gel-like aqueous substances that contains all cell components </li></ul><ul><li>Cytoplasm has three main functions, energy, storage, and manufacturing </li></ul>
  3. 3. CELL (PLASMA) MEMBRANE <ul><li>Function: </li></ul><ul><li>allows exchange of small molecules from one side of the membrane to the other and is – SELECTIVELY PERMEABLE </li></ul><ul><li>Prevents outside interference </li></ul>
  4. 4. CYTOSKELETON <ul><li>General: Maintaining cell shape and size. Help with movement of organelles inside cell </li></ul><ul><li>Microfilament: </li></ul><ul><ul><li>Aid in cellular movement and contraction (muscle) </li></ul></ul><ul><li>Microtubule </li></ul><ul><ul><li>Assist in cell division (centrioles) </li></ul></ul>
  5. 5. THE NUCLEUS <ul><li>The nucleus stores and processes genetic information in the form of DNA and RNA. </li></ul><ul><li>The nuclear envelope separates the nucleus from outside intrusions. </li></ul><ul><li>Nuclear pores transport of information </li></ul><ul><li>Nucleolus housed in nucleus and produces ribosomes </li></ul>
  6. 6. MITOCHONDRIA <ul><li>Within the cytoplasm of the cell </li></ul><ul><li>The cell ’s “ Power House ” </li></ul><ul><li>Site for CELLULAR RESPIRATION and generates fuel for the cell's activities in the form of ATP </li></ul><ul><li>They convert energy into forms that are usable by the cell. </li></ul>
  7. 7. ENDOPLASMIC RETICULUM <ul><li>Pathway of membranes or tubules around the cell – TRANSPORT SYSTEM </li></ul><ul><li>Rough E.R .: synthesizes or makes proteins b/c of ribosomes – will be transported to golgi apparatus </li></ul><ul><li>Smooth E.R .: manufactures steroids </li></ul>
  8. 8. RIBOSOME – The Laborer <ul><li>Function: </li></ul><ul><li>Produces and assembles proteins by bringing RNA and amino acids together. </li></ul><ul><li>- produced in nucleolus and embedded on rough E.R </li></ul>
  9. 9. GOLGI APPARATUS <ul><li>Golgi apparatus is essentially a protein “Packaging Plant” </li></ul><ul><li>Manufactures, packages and transports proteins and other molecules </li></ul><ul><ul><li>Works with E.R. in altering or modifying proteins for export </li></ul></ul>
  10. 10. Transport of Proteins
  11. 11. Animal Cell vs. Plant <ul><li>Generalized Animal Cell </li></ul><ul><ul><li>Lysosome </li></ul></ul><ul><li>Generalize Plant Cell </li></ul><ul><ul><li>Cell Wall </li></ul></ul><ul><ul><li>Vacuole </li></ul></ul><ul><ul><li>Chloroplast </li></ul></ul>
  12. 12. LYSOSOME <ul><li>Located throughout cytoplasm </li></ul><ul><li>“ Suicide bags” – Contains digestive enzymes that break down or digest macromolecules, old organelles, viruses and bacteria that are unwanted by the cell </li></ul>
  13. 13. CELL WALL <ul><li>Surrounds outside of plant cells </li></ul><ul><li>Composed of long strands of the polysaccharide, cellulose </li></ul><ul><ul><li>Helps keep plant cells rigid </li></ul></ul><ul><li>Functions: </li></ul><ul><li>to protect the cell against injury and invasion from harmful materials. </li></ul><ul><li>Provides cellular support </li></ul>
  14. 14. CHLOROPLAST <ul><li>Flattened membranous sac found in cytoplasm of plant cells </li></ul><ul><li>Chloroplast </li></ul><ul><ul><li>Site for PHOTOSYNTHESIS where plants use CO 2 , water and sunlight to produce energy in the form of glucose </li></ul></ul><ul><ul><li>Contain the light-sensitive pigments, called chlorophyll a. </li></ul></ul>
  15. 15. CENTRAL VACUOLE <ul><li>Plant: Central location of cell (most typical) 90% </li></ul><ul><li>Functions in storage, digestion and releasing of waste products </li></ul><ul><li>Types: </li></ul><ul><ul><li>STORAGE : ions, molecules, water </li></ul></ul>
