Photosynthesis Lab
Purpose:
What will happen if leaves were cut off from sunlight? Would they continue producing glucose? In this lab we will be taking test plants to see if the leaves were cut off from sunlight if they would continue making glucose. Plants need glucose to produce energy (ATP). If a plant doesn't have energy, it dies. Have you ever put a plant in your backyard in a shady place and a few days later it wilted and died? That's because not enough glucose is produced in the plant to go through photosynthesis which produces ATP for an energy source.
Materials:
Black paper Scissors
Iodine Tweezers
Test tubes Green plant
Beaker 400ml Green/red plant
Tape Blue paper
Petri-dishes Alchohol
Hypothesis: with some of the light cut off, the chlorophyl will not produce glucose
Results:

Hypothesis: with some of the light cut off, the chlorophyl will not produce glucose
Results:
Conclusion: We have concluded after we tested the plant that not much glucose was produced from the chlorophyl. My hypothesis was correct. We took different types of paper and covered the leaves and then recorded the results. Since black paper attracks sunlight, that leaf had the most glucose produced. The others leaves didn't produce much glucose due to the type of paper covering the leaf. The experiment was successful because we were correct on our hypothesis and we gathered enough information on how leaves can change color and their production rate of glucose based on the outside environment.
