Why do plants need to ensure that there is sufficient intake of oxygen
  • 1 answers

Meghna Thapar 5 years, 6 months ago

Oxygen, for plants, is essential because it makes the process of respiration more efficient (known as aerobic respiration). Plant cells are respiring constantly. But, during times when they can't access light, most plants respire more than they photosynthesize, so they take in more oxygen than they produce. Respiration is the process of oxidation of food substances that release carbon dioxide; it takes place throughout the day. Photosynthesis takes place during day in presence of Sunlight only. Hence, plants release oxygen during day only while carbon dioxide is released during night.
