Presentation Transcript

  1. Cellular Organelles:How is structure related to function?

  2. PlasmaMembrane • Structures: • Phospholipidbilayer • Integral Proteins • Glycolipids • Peripheral Proteins • Functions • Control what enters and leaves • Identifies the cell

  3. Nucleus • Structures: • Nuclear Envelope • Membrane • Pores • Chromatin • Nucleolus • Functions: • Control what leaves/enters the nucleus • Storage of DNA • Manufacture Ribosomes

  4. Ribosomes • Structures: • Large Subunit • Small Subunit • RNA • Docking stations for tRNA • Protein • Functions: • Dock tRNA to the RNA code • Drop off Amino Acids • Generate proteins

  5. Endoplasmic reticulum • Structures: • Large membrane channels • Small membrane tubes • Ribosomes • Functions • Proteins are made and enter the channels • Directed towards the outside of the cell

  6. Golgi Apparatus • Structures: • Membrane Sacs (Cisternae) • Incoming vesicles • Outgoing vesicles • Functions: • Receive proteins • Process proteins • Package proteins • Ship them out of the cell

  7. Vesicles • Structures: • Phospholipidbilayer • Contents • Enzymes • Food • Water • Functions: • Breakdown old cell parts • Storage

  8. Structures: Outer Membrane Inner Membrane (Cristae) Matrix Functions: Cellular Respiration Concentration Gradient ATP Synthase embedded in the cristae Mitochondria

  9. Structure: Inner/Outer Membrane Stroma Grana Thylakoids Functions: Concentration gradient Pigments for Photosynthesis embedded in the membranes Make sugars! Chloroplasts
