If a plant is releasing Co2
and taking in 02 during the day, does it mean that
there is no photosynthesis occuring? Justify your answer.
Answers
◼If a plant is releasing CO₂ and taking O₂ during day,that doesn't mean that photosynthesis is not occurring.
◼Respiration releases Co₂.
◼Plants are living beings and metabolism constantly burns the food taking oxygen and releasing carbon dioxide.
◼If plants give out carbon dioxide in the day, it is also possible that there is no breakdown of carbon and water.
◼So, it is a wrong statement that if a plant releases carbon dioxide and takes in oxygen during day time, no photosynthesis is taking place.
Yes, you are right. We can say that no photosynthesis occurs during night.
only respiration occurs during night. And photosynthesis during day.
Justification: We know that sunlight is the most important for photosynthesis. which is only present during day and not during night.
So no photosynthesis can take place during night .
therefore plants respire during night and no photosynthesis occurs during night.
Simple....
I hope you understood.
