thylakoids
• Thylakoids stacked in piles called granum
• Between grana are intergranal lamellae
Stroma
• Fluid-filled matrix
• Contains starch grains, oil droplets, DNA and ribosomes
, How leaves are adapted for
photosynthesis
• Large surface area to absorb as much sunlight as
possible
• Thin for a short diffusion distance for gas exchange
• Transparent cuticle to let light through to the
mesophyll cells beneath
• Long narrow mesophyll cells packed with
chloroplasts to collect sunlight
• Numerous stomata for gas exchange
• Air spaces in mesophyll layer to allow exchange of
carbon dioxide and oxygen
• Network of xylem that brings water to the leaf cells
• Phloem that carries away the sugars produced
, Photosynthesis- photosystems
• On the thylakoid membranes, chlorophyll molecules are arranged into c
called photosystems I and II
LDR (light dependent reaction)
• Involves capture of light energy to add inorganic phosphate to ADP to m
and to split water into hydrogen ions, oxygen and electrons
• Splitting of water is caused by light and so is referred to as PHOTOLYSIS
• Produces:
ATP
Reduced NADP
Oxygen
• Referred to as non-cyclic photophosphorylation
