How does oxygen enter a leaf

Topics: ScienceHealth


Plant respiration uses up oxygen and produces carbon dioxide. Oxygen is dissolved in aqueous solutions (at 25C, the concentration is 250uM) and is available in the intercellular spaces of the plant. The amount of oxygen required in respiration is around 1uM so there is no lack of oxygen for the plant cells in daytime or nighttime.
