Question

All plants give out oxygen during day and carbon dioxide during night. Give reason

Answer 1

Answer:

Hence, there is a continuous release of carbon dioxide during the day time and night time. However, during daytime, the waste carbon dioxide released during respiration is utilised by the plants for photosynthesis. As a result, it appears as if plants give out oxygen only during the day and carbon dioxide during night.

Question:

All plants give out oxygen during day and carbon dioxide during night. Give reason

Answer:

Generally, photosynthesis takes place in day time due to the presence of sunlight. This doesn't means respiration doesnt take place. This implies that the carbon dioxide produced is used for the process of photosynthesis. The remaining carbon dioxide is given out during night. That is the reason why it is advised not to sleep under trees during night.
