Light-response curves of photosynthetic carbon
fixation in sun and shade plants. Typically, shade plants have a low light
compensation point and have lower maximum photosynthetic rates than sun plants
this is because respiration rates in shade plants are very low; which of the
following graph is correct?

The large amounts of energy absorbed by the pigments if this energy cannot be stored by photochemistry, this is why a protection mechanism is needed Protection against photodamage is a multilevel process what role does the first line of defense play to suppress from damage?
