All plants give out oxygen during day and carbon dioxide duringnight”. Do you agree with this statement? Give reason.
all living beings need oxygen for respiration.
plants as well as animals take up oxygen and give out carbondioxide but due to the presence of sunlight during the day plants take the Co2 released by them for the preparation of their food but this process do not happen during night as their is no presence of sunlight during night and hence they are said to release Co2 at night..!!
AS WE KNOW THAT PHOTOSYNTHESIS TAKES PLACE IN LIGHT .IN DAY BOTH RESPIRATION AND PHOTOSYNTHESIS TAKES PLACE .THE WASTE C02 IS RELEASED DURING RESPIRATION IS UTILISED BY PLANTS FOR PHOTOSYNTHESIS THEREFORE ONLY O2 IS RELEASED DURING DAY AND AT NIGHT NO LIGHT IS PRESENT SO NO PHOSYNTHESIS TAKES PLACE THEREFORE ONLYCO2 IS RELEASED OUT.........
YES I AGREE WITH THIS STATEMENT. BOTH RESPIRATION AND PHOTOSYNTHESIS TAKES PLACE DURING THE DAY.SINCE THE RATE OF RESPIRATION IS SLOW HENCE CO2 RELEASED IS USED UP BY PLANTS IN PHOTOSYNTHESIS.SINCE THE PHOTOSYNTHESIS IS FAST SO FEW AMOUNTS OF OL2 IS USED UP BY PLANTS IN RESPIRATION.DURING THE NIGHT SINCE THERE IS NO LIGHT HENCE NO PHOTOSYNTHESIS TAKES PLACE AND ONLY CO2 IS RELEASED.
The amount of oxygen the plants in your bedroom use at night is trivial. Think about the earth as a giant bedroom and you’ll see that animals would be in pretty big trouble if plants used up a significant amount of oxygen every night.
