Photosynthesis

• Chloroplasts

  Organelles where photosynthesis occurs
• Fluid within Chloroplast

  Stroma
• Stroma

  Site of light-independent stage of photosynthesis
• Thylakoids

  Flattened fluid-filled sacs

  • Stack up to form Grana
• Lamellae

  Membranous channels connecting Grana

  • Ensures stacks are connected but distanced from each other
• Loop of DNA

  Codes for some of the chloroplast proteins

  • Produced at the 70S ribosomes
• Starch grains

  Starch storing sugars formed during photosynthesis.
• Site of light-independent stage

  Thylakoid membranes and thylakoid spaces.
• Electrons

  Donated by water molecules

  • Accepted by NADP molecules forming NADPH
• Photosystems

  Light harvesting clusters of pigment molecules
