chloroplasts

• thylakoid membrane:

  system of interconnected flattened fluid filled sacs.

  • proteins embedded in membranes, involved in light independent reaction
• thylakoid space:

  fluid within membrane sacs that contain enzymes for photolysis
• outer membrane:

  freely permeable to molecules like carbon dioxide or water
• inner membrane:

  contains transporter molecules (membrane proteins that regulate passage of substances in/out a cell)
• granum:

  stack of thylakoid membranes
• stroma:


  fluid surrounding thylakoid membranes, contains membranes needed to carry light independent reactions
• starch grain:

  stores products of photosynthesis
