CHLOROPLAST ADAPTIONS

• ADAPTIONS OF CHLOROPLAST?

  • thylakoid membrane
  • protein network in grana
  • granal membrane has ATP synthase channels
  • chloroplasts contain DNA and ribosomes
• WHAT DOES THE THYLAKOID MEMBRANE DO?

  provide a large SA for attachment
• WHAT ATTACHES TO THE THYLAKOID MEMBRANE?

  chlorophyll, electron carriers, enzymes
• WHAT DOES THE LARGE PROTEIN NETWORK IN THE GRANA DO?

  hold chlorophyll in position for maximum absorption of sunlight
• WHAT DO GRANAL MEMBRANES HAVE ATP SYNTHASE CHANNELS FOR?

  • catalyse ATP production
  • are selectively permeable so create a proton gradient
• WHAT DO CHLOROPLASTS HAVE DNA AND RIBOSOMES FOR?

  quickly manufacture some proteins for light-dependent reactions
