Ans:
You are looking a several living plant cells, some from the leaves, some
from fruits, some from the stems, and some from the roots. Which of
the cells will have functional mitochondria?
Ans: All the cells (leaves, roots, stems, and fruits) will have
functional mitochondria

Normal atmospheric conditions are 20% O and 22 2390 ppm CO . You
expose C3 plants to different environments varying in CO and O
conditions. Which atmospheric conditions will show the lowest rate of
photorespiration?
Ans: 10% O2 , 700 ppm CO2
You measure the photorespiration rates of a C3 and a C4 plant growing
in normal atmospheric conditions. You then reduce the oxygen
concentration by half. Both the C3 and the C4 plants will show a
reduction in photorespiration. Which one will show the greatest
reduction in photorespiration?
Ans: The C3 plant
In the late 1800's, a researcher named Engelmann was interested in
how color of light would affect photosynthesis. He shown while light
through a prism to separate it into different wavelength. This light was
then absorbed by Spirogyra algae. The algae released oxygen, 2w hich
attracted bacteria (the more photosynthesis = more O = more
bacteria). Engelmann was able to tell what colors of light stimulated
the most photosynthesis by the amount of bacteria each color of light
attracted. Below are four possible results for the Engelmann
experiment, which is the actual result of his experiment?
Ans: D high low high
