The distinction between C3, C4, and CAM plants is the intermediate substance that is made prior to the Calvin Cycle. These modifications allow C3 plants to grow in cooler regions, C4 plants to grow in hot climates, and CAM plants to grow in very dry environments.

One similarity about the chlorophyll content between the low and moderate light seedlings is:
A Both seedling groups have about the same amount of chlorophyll content for the first 12 hours of growth.
B Both seedling groups have the exact same amount of chlorophyll content for the first 8 hours of growth.
C Both seedling groups have the exact same amount of chlorophyll content for the first 3 to 5 hours of growth.
D Both seedling groups have the exact same amount of chlorophyll content for the last 24 hours of growth.

One of the differences in the seedling groups is
A after 12 hours moderate light plants have a greater chlorophyll content than the low light plants.
B after 8 hours moderate light plants have a greater chlorophyll content than the low light plants.
C after 5 hours moderate light plants have a greater chlorophyll content than the low light plants.
D after 3 hours moderate light plants have a greater chlorophyll content than the low light plants.

To which of the two lighting conditions would you expose seedlings if you wanted to maximize the rate of photosynthesis in the plants as well as minimizing your costs for electricity to light the plants in the greenhouse?
A Low light only.
B Moderate light only.
C Low light for the first 12 hours and then moderate light afterwards.
D Moderate light for the first 12 hours and then low light afterwards.
