Think about what goes into, and what comes out of photosynthesis. Carbon
dioxide is a...
a. Substrate of the chemical reactions in photosynthesis
b. Product of the chemical reactions in photosynthesis
c. Enzyme in the chemical reactions in photosynthesis
d. Location in the cell that photosynthesis happens Right Ans - a. Substrate

This is a microscopic photo of a hole on a plant leaf that allow CO2 to come
into the leaf, but also allow water to escape. These holes are called Stomata.
During hot parts of the day the leaf stomata close to prevent loss of water.
With stomata closed, less carbon dioxide is available to the cells inside the
leaf, the rate (amount) of photosynthesis will...
a. Increase (go up), increasing the growth of the plant
b. Decrease (go down), decreasing the growth of the plant
c. Decrease (go down), increasing the growth of the plant
d. Increase (go up), decreasing the growth of the plant
e. Stay the same Right Ans - b. Decrease (go down), decreasing the growth
of the plant

a...
a. Substrate of the chemical reactions in photosynthesis
b. Product of the chemical reactions in photosynthesis
c. Enzyme in the chemical reactions in photosynthesis
d. Location in the cell that performs photosynthesis Right Ans - a. Substrate
of the chemical reactions in photosynthesis
, After a rainstorm, when there is more water available to plants, the rate of
photosynthesis will...
a. Increase (go up), increasing the growth of the plant
b. Increase (go up), decreasing the growth of the plant
c. Decrease (go down), decreasing the growth of the plant
d. Decrease (go down), increasing the growth of the plant
e. Stay the same Right Ans - a. Increase (go up), increasing the growth of
the plant
In the winter, plants grow much slower, why? Cold temperatures will...
a. Denature the enzymes that do photosynthesis
b. Make photosynthesis enzymes disappear
c. Slow the enzymes down that do photosynthesis
d. Speed the enzymes up that do photosynthesis Right Ans - c. Slow the
enzymes down that do photosynthesis
An acidic environment (beyond optimal pH) will...
a. Denature enzymes (Change their shape)
b. Make enzymes disappear
c. Slows enzymes down - they react much more slowly
d. Speed enzymes up - they react much faster Right Ans - a. Denature
enzymes (changes their shape)
For trees growing where there is acid rain, the rate of photosynthesis will...
a. Increase (go up), increasing the growth of the plant
b. Increase (go up), decreasing the growth of the plant
c. Decrease (go down), decreasing the growth of the plant
d. Decrease (go down), increasing the growth of the plant
e. Stay the same Right Ans - c. Decrease (go down), decreasing the growth
of the plant
Which of these organisms do BOTH photosynthesis AND cellular respiration?
a. Plants
b. Animals
c. Both plants and animals
d. No organism can do both photosynthesis and cellular respiration Right
Ans - a. Plants
Which of these are FALSE?
