Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When compared to the amount of oxygen produced in the process of photosynthesis, the amount of oxygen used in plant respiration is:
A
about the same
B
less
C
more
D
much more
Explanation: 

Detailed explanation-1: -This results in the production of the greater amount of oxygen by photosynthesis than the amount needed for respiration. Hence there is build of oxygen in cells. Owing to the lower rate of respiration as compared to that of photosynthesis during the day time, the ratio of oxygen production to its consumption is 10:1.

Detailed explanation-2: -Plant will die. 2. Storage food comes to end.

Detailed explanation-3: -During respiration, carbon dioxide is released back into the atmosphere, but this is roughly half of what is taken up from the atmosphere in photosynthesis. Similarly, more oxygen is given off during photosynthesis than is used up in respiration.

Detailed explanation-4: -By actually measuring the volume of oxygen gas produced by a plant, you can work out the rate at which photosynthesis is happening. The more oxygen given off, the higher (or faster) the rate of photosynthesis.

Detailed explanation-5: -Since the plants use the sugar they make for more than just energy, they produce more oxygen than they use. The plants use those sugars like we do when we consume them, for energy. Plants use the sugars they make by oxidizing them (with O2, just like us) to release the energy stored in the bonds.
