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.
Through photosynthesis, plants use carbon dioxide and create oxygen. This means that respiration can be thought of as photosynthesis in reverse. One major difference between the two is that plants respire constantly, but only photosynthesize when they are in the light. In dark conditions, a plant would respire, but not photosynthesize.
