Homework answers / question archive / Azusa Pacific University BIOL 101 Case #3 “Be Careful How Much Electricity You Use” 1)Where do we find the plants that perform the highest percentage of the Earth’s photosynthesis? Why? If plants use the ATP they make from sunlight to produce glucose, where do they get the ATP to do all of the other jobs around the cell that require energy? If plants are called producers or autotrophs, what are humans called? Why? Why do bruises start out being red in color and then change to black, purple, blue, and even green?     Cell Structure and Function Describe the “Cell Theory”
