1. The equations are the opposite of each other. Photosynthesis uses sunlight to convert foods from carbon dioxide and water light energy into a six-carbon simple sugar, and also produces oxygen. While cellular respiration uses the oxygen and sugars to release chemical energy for the cells to use, and also produces water and carbon dioxide. 2. The rate at which photosynthesis occurs needs to be higher because photosynthesis creates building blocks for growth. (six-carbon simple sugars) Cellular respiration is also needed for the growth, but first it needs to break down the simple sugars to create and distribute the energy. 3.a. More light should increase the rate of photosynthesis …show more content…
Data Analysis Now use the computer to create a bar graph of the average photosynthetic rates of canopy and understory leaves under high and low light conditions. Paste a copy of your graph in the space below. Ask your teacher if you have questions about using the software to create the graph. You graph must include a title and properly labeled axes. 7. No, at high light, canopy leaves are better than understory leaves, but understory leaves do better than canopy leaves at low light. At their best, however, understory leaves cannot attain photosynthesis rates of canopy leaves. 8. 1. 9. Because there is a 1:1 relationship between the use of carbon dioxide and the production of oxygen, we can assume that the amount of oxygen being used or produced is equivalent to the amount of carbon dioxide being produced or used.
