No, carbon dioxide can be produced in night also. Not all plants give oxygen at day and co2 at night. Oxygen is released during day because of photosynthesis. co2 is released due to lack of sunlight plants cant make photosynthesis.

All Plants give out oxygen during Day and carbondioxide during Night. Do you agree with statement? Give Reason.

This statement is incomplete."All plants give out oxygen during day and carbon dioxide during night"

Explanation :

Photosynthesis occursonly during day time.During this time oxygen is produced . Some oxygen is used for respiration and rest of oxygen is diffused out into air.Carbon dioxide produced during day time by respiration is used in photosynthesis.

But at night time, no photosynthesis occurs and hence no oxygen is producedoxygen from air diffuses into leaves to carry out respiration and carbon dioxide produced by respiration diffuses out into air.

Desert plants take up carbon dioxide at night and prepare an intermediate which is acted upon by the energy absorbed by the chlorophyll during the day.

there are three exceptions to this statement:- 1. non- green plants do not perform photosynthesis.2. desert plants prepare an intermediate during night.3. green plants also produce carbon dioxide during respiration but the net amount of oxygen is greater.

No, I don't agree with the given statement.When plants respire they take in carbon dioxide and give out oxygen. These gases are taken in and given out whenever plants respire.. For example desert plants take up Co2 at night and prepare an intermediate which is acted upon by the energy absorbed by chlorophyll during the day.
