It's the comment equivalent of the 'Lorem Ipsum' dummy text beloved of the printing and typesetting industry, when they need specimen words to illustrate how a piece of text would look: Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua (it's not Latin, although it has roots in that language).
Something similar happens in plants. When the rate of respiration is more than the rate of photosynthesis, the biomolecules present in plants break down to compensate the reduced rate of photosynthesis. This results in loss of dry weight of the plant. Views Â· View Upvotes.
Photorespiration, or 'photo-respiration', is a process in plant metabolism. A sugar has oxygen added to it by the enzyme (RuBisCO), instead of carbon dioxide during normal photosynthesis.This process reduces efficiency of photosynthesis.hotorespiration can occur when carbon dioxide levels are low, for example, when the stomata are closed to prevent water loss during drought.
