Number of organelles required for photorespiration is

The number of organelles required for photorespiration is three.
Photorespiration refers to a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis.
Photorespiration involves a complex network of enzyme reactions that exchange metabolites between chloroplasts, leaf peroxisomes and mitochondria, and these are the three organelles required for this process.
