What is Photosynthesis?

This week, students learned the in-depth process of how plants make their food, a sugar called glucose. The learned that plant seeds have enough chemical energy to sprout and do very well, even in total darkness for several days. In fact, our seeds in total darkness even out-performed the ones in light (due to less evaporation). However, yesterday we observed that our wheat plants in the total darkness, although growing still, look sickly. Students learned that they are not green because the chlorophyll isn't able to take the CO2, water, and light to produce glucose. We decided to take some of the plants in darkness and put them in the light, while also taking some from the light and putting them in darkness. We will see if over a few days we see changes.
