Roles of chloroplast structure

• 'Inner membrane with transport proteins' How does this adaptation help?

  Controls molecules travelling between cytoplasm and stroma
• 'Many grana'. How does this adaptation help?


  Large SA for photosynthetic pigments and ATP synthase used in LDR
• 'Photosynthetic pigments, e.g. chlorophyll a' How does this help?

  Arranged in photosystems, allows max light absorption
• 'Proteins in grana' How does this help?

  Hold photosystem in place
• 'Fluid-filled stroma' How does this help?


  Contains enzymes needed for LIR
• 'Grana surrounded by stroma' How does this help?


  Products made in LDR in grana can pass into stroma to be used in LIR
• 'Chloroplast, DNA and ribosome' How does this help?


  Can make some proteins needed for photosynthesis
