Question

If carbon dioxide is completely removed from a plant's environment, what would you expect to happen to the plant's production of high-energy sugars?

Answer 1

To produce glucose that can fuel a plant's activities, plants must take in carbon dioxide to perform photosynthesis.

$6CO_{2} + 6H_{2}O + sunlight ---> C_{6}H_{12}O_{6} + 6O_{2}$

Without carbon dioxide, the plant's cells would not be able to perform photosynthesis and produce glucose. Photosynthesis would cease and the plant would not be able to produce high energy sugars- glucose.
