Question

" All plants give out O₂ during day and CO₂ during night", what is wrong with this statement?

Answer 1

Gas released by plants:

1. During photosynthesis, carbon dioxide and water are the raw materials required to produce organic food and oxygen.
2. Therefore, plants respire every time and expel CO₂ but oxygen is released only in the daytime during the photosynthesis
3. In plants, the gaseous exchange takes place under the provided circumstances of the environment and the requirements of the plants:
4. During the daytime, carbon dioxide is absorbed by the plants for photosynthesis. Therefore, the gas expelled is oxygen.
5. But at night, due to the absence of sunlight, photosynthesis stops, and carbon dioxide formed during respiration is released
6. Therefore, all plants give out O₂ during the day and CO₂ for the entire time.
