7. Explain photorespiration and how the enzyme rubisco plays a major role in that process during photosynthesis?
vascular cambium
photo respiration occurs usually in times of drought. limited water forces the plant to close stomata - therefore blocking co2. with lo concentrations of co2 and high concentrations of 02 - the enzyme rubisco starts to bind 02 instead of co2. this pr
