Question :
Where do plants get their oxygen for cellular respiration ?Submitted on 20/4/2024 | Answered by Vandana RanaAnswer :
Plants do not obtain oxygen for cellular respiration from the external environment. Instead, during photosynthesis, plants produce oxygen as a byproduct.This oxygen is released into the atmosphere as a waste product of the photosynthetic process. During cellular respiration, plants use the oxygen that was produced during photosynthesis to break down sugars and generate energy. The oxygen used in cellular respiration comes from within the plant's cells, not from the external environment.
