    Q.

    If carbon dioxide is completely removed from a plant’s environment, what would you expect to happen to the plant’s production of Glucose?

    answer choices

    Glucose production will increase.

    Glucose will not be produced.

    The rate of glucose production will decrease .

    Fewer glucose will be produced at first, but then the plant will recover.

    Q. If we enclosed a plant in an air-proof bottle, what would happen to the rate of photosynthesis 
    answer choices
    Gradually slow down to zero because CO2 is used up
    Shows a constant rate as long as the light remains on
    Gradually speeds up because O2 builds up
