Elodea and Photosynthesis


Today we started of by letting Mr. Finley check our homework. Then for the students who were absent on Friday, Mr. Finley chose two people to catch up those students. Next he gave the tests back. Mr. Finley then gave stickers to the classmates who had the top 5 grades in the class. The equation for photosynthesis is 6Co2+6H2O+Light energy--->C6H12O6+6O2. Plants get CO2 from the stoma on the plant. The organelle in plants that is responsible for photosynthesis is the chloroplasts. Chlorophyll is the pigment found in in the organelle that absorbs light to power. If a plant were under water and was photosynthesizing, oxygen would be visible from the plant. The following picture in the top right corner is a diagram of photosynthesis. We need light energy to trigger a reaction in photosynthesis. Mostly photosynthesis doesn't happen in the dark.
