Here are some study aids to help you with photosynthesis and respiration. They're not nearly as good as the DNA handouts, but maybe they will help you guys study. You can also find more detailed notes here and here. I'll keep searching.

Mission 1: The Mighty Mitochondria!!
Mission Objectives. You should be able to...
1. Draw and annotate the inside of a mitochondrion.
2. Explain how cellular respiration is the controlled release of energy from organic compounds.
3. Compare and contrast anaerobic and aerobic respiration.
4. Describe the process of cellular respiration as it relates to a mitochondrion.
The mitochondria are the sites where energy is produced to power the cell...and everything else. Muscle cells have lots and lots of mitochondria; can you guess why? Neurons do not have as many; can you guess why?
In order to get into cellular respiration, you need to understand the structures and functions of the inside of a mitochondrion. Where does each component of cellular respiration take place? We will come back to this in Mission 2.
Task #1: Draw and annotate the inside of a mitochondrion. Describe and define the structures and functions of the following: (a) matrix, (b) cristae, (c) inner membrane, (d) outer membrane, and (e) ribosomes. Please make it large enough so that I can see the structures and can read the functions. Here is your model. I want a nice, neat, colorful mitochondria.
What you need to listen for/learn: (a) the differences between aerobic and anaerobic respiration, (b) where the energy is in glucose and where it goes when bonds break, (c) why respiration must take place within the mitochondria (and what happens if it didn't), (e) summarize the three steps of respiration and include the location and products of each step, (f) why anaerobic respiration sometimes must take place and its effects on the body, (g) explain the difference between alcoholic fermentation and lactic acid fermentation, and (f) relate the steps of respiration to the structure of the inner mitochondrion.
**Also, take note of the roles of NADH, FADH, and NAD+, as well as oxygen, protons and electrons in the respiration process
1. Draw and annotate the inside of a chloroplast.
2. Describe the process of photosynthesis.
3. State what wavelengths of light is used by plants in photosynthesis.
4. Describe the process of photosynthesis.
Photosynthesis is the converse process of respiration. Here, light energy is converted into glucose and oxygen. It takes place in the chloroplasts of plants. The pigment chlorophyll is what makes plants green. Here is an image of the electromagnetic spectrum, courtesy of your textbook.
Light-independent reactions (LIR) do not necessarily require sunlight in order to take place. The ATP and hydrogen are used as forms of chemical energy to convert carbon dioxide and water into useful molecules for the plant. It takes six carbon dioxide molecules to form one glucose molecule.
Fixation is the process by which this happens. Carbon dioxide and water are fixed into glucose and oxygen is produced as a waste product. Fixation requires energy, which comes from the ATP and hydrogen created in the LDR, which came from sunlight.
The rate of photosynthesis is dependent upon environmental factors, such as intensity of light and air temperature. During the daytime, the rate may be very high for a particular plant. At night, the rate of photosynthesis may drop to zero. Measuring the rate of oxygen production or carbon dioxide intake is an indicator of photosynthetic rate as long as a correction is made for cell respiration.
