What is the BEST explanation for why thylakoid membranes are flat and stacked?
A. to fit more into a chloroplast
B. to increase surface area for light absorption and cross-
membrane traffic
C. to increase the color of the leaf as camouflage from herbivores
D. to hold more ATP
Why do land plants have stomates (sometimes called stomata)?
a. To allow plants to take in carbon dioxide from the atmosphere.
b. All of the choices are true; none are false.
c. To control water loss while allowing for the uptake of some raw materials of photosynthesis.
d. They allow the plant to have some control over transpiration rates.
Many scientists are concerned because CO2 levels in the atmosphere appear to be increasing. If this happens, how do you think plants and the atmosphere will affect each other? Make sure you include both respiration and photosynthesis in your answer.

- Which statement best explains the relationship between the amount of sunlight a plant receives and the flow of energy into and out of the plant system? A An increase in the amount of sunlight adds more energy to the system and increases the rate of photosynthesis.
