vascular cambium
28. In which region would an ntercalary meristem be found?

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
