Aquatic plants and animals and the acidification of our oceans This experiment was performed to ascertain the effect of aquatic plants on the acidity levels of our oceans. Carbon dioxide levels in our atmosphere have been on the rise mainly due to the burning of fossil fuel and deforestation. The results of this experiment will ascertain whether aquatic plants help to reduce the acidification of our oceans, via the process of photosynthesis.
The effect of Different Light Wavelengths on Photosynthesis Light energy is the key to photosynthesis. A relatively narrow portion or the visible light spectrum is most active in photosynthesis. By performing experiments that selectively filter out different wavelengths of light you can learn about which wavelengths are most active in driving photosynthesis.

What side of a plant's leaf takes in atmospheric gases? Ten (10) students say the top of the leaf takes in gases because when rain and watering cans water plants it comes from above and hits the top of the plant leaves first. Ten (10) say the bottom of the leaf takes in gases because after observing the leaves from each plant the bottom of the leaves were more veiny and the skin of the bottom leaves seemed thinner. The top of the plant leaf had a t
