PHOTOSYNTHESIS
BIOLOGY 3.2
, CHLOROPLASTS
Photosynthesis occurs in chloroplasts, primarily in the palisade mesophyll cells and a little in the spongy mesophyl
because these cells contain lots of chloroplasts. Guard cells are the only epidermal cell containing chloroplasts.
Chloroplasts are transducers: they change light energy (photons) into chemical energy through photosynthesis. In
Margullis discovered that the base sequence of chloroplasts indicate they are descended from cyanobacteria by u
endosymbiosis.
Chloroplasts contain different pigments which absorb light at different wavelengths. These can be classified into 2
chlorophyll (chlorophyll a and chlorophyll b), and carotenoid (carotene and xanthophyll's).
Phaeophytin is the blue grey breakdown product of chlorophyll. It has no magnesium but it can still absorb light an
electrons in photosystem II. But reflect green which gives leaves their colour.
These pigments can organise themselves to receive as much light as possible at different intensities. In low light th
evenly through the cytoplasm and at high light they form vertical columns along the cell wall side on to the light to
damage from overexposure.
