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.
Quick Answer. During photosynthesis, plants take in carbon dioxide and water, disassemble the molecules and convert them into sugar and oxygen. The water molecules are split into hydrogen and oxygen, and the hydrogen joins carbon dioxide to create sugars. The excess oxygen is released into the atmosphere during the respiration cycle.
