Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Carbon dioxide is removed from a plant’s environment, what would you expect to happen to the plant’s production of high-energy sugars?
A
Fewer sugars will be produced because photosynthesis cannot occur.
B
More sugars will be produced and photosynthesis will continue to occur.
C
The same number of sugars will be produced but without carbon dioxide.
D
Carbon dioxide does not affect the production of high-energy sugars in plants.
Explanation: 

Detailed explanation-1: -The same number of sugars will be produced but without carbon dioxide. Carbon dioxide does not affect the production of high-energy sugars in plants.

Detailed explanation-2: -If carbon dioxide is completely removed from a plant’s environment, we would expect the plant to stop producing high-energy sugars altogether. CO2 is necessary for the plant to perform photosynthesis, meaning without CO2 the plant has no way to obtain energy-it will likely die in this scenario.

Detailed explanation-3: -It is not unusual for plants to stop taking in carbon dioxide to uptake small amounts of oxygen at night. In the event that plants cease to take up CO2 all together, they will cease to convert sunlight into carbohydrates, and die.

Detailed explanation-4: -What will happen if green plants stop taking in carbon dioxide & release oxygen? If the green plants stopped taking carbon dioxide, they will die and the human beings and animals would not get oxygen and would die too.

Detailed explanation-5: -Photosynthesis increases as CO2 increases until some saturating concentration, which is typically around 1, 000 ppm. Enriching the air with CO2 enables plants to more effectively utilize light, resulting in an increase in the light saturation point.
