Post-Lab Questions
1. What did the different colored bands signify in each solvent for Part 1? What pigments can you associate them with?

2. What is the osmolarity fluid used in Part 2? Why is this important? Why is it essential to

keep it cool?

3. How could you modify this experiment to show the effects of different wavelengths of light on the photosynthetic rate?

4. Some plants (grasses) tend to contain a greater concentration of chlorophyll than others

(pines). Can you develop a hypothesis to explain this? Would it be testable?

5. Saliva does not contain amylase until babies are two months old. How could this affect an infant’s
digestive requirements?
