1. Biology 2 Packet II Lab Food Production in Plants

2. Copy this information on Pg. 25 in your Packet: Plants make glucose (their food) inside their bodies. This is called photosynthesis! Every living thing needs food for energy to survive. No Food = Death  Plants store energy as starch, which is a whole bunch of glucose linked together: Starch = Glucose-Glucose-Glucose-Glucose Plants combines CO2 (from air) and water (from ground) to make Glucose. Plants use the energy from the sun to convert CO2 and water into glucose! No sun = No photosynthesis! When Iodine and starch mix, solution turns purple.

3. Fresh Leaf From Plant

4. Leaf after two days in the Dark

5. Set up for Boiling Leaf in Ethanol

6. Purpose of Ethanol: To remove the Chlorophyll in leaves. Chlorophyll is what captures sunlight for photosynthesis!
