the stomata opens. It occurs when water exits through the stomata when the plant takes in carbon dioxide. Part 2- Slides

Root Monocot Stem Monocot Root monocot Part 3- Photosynthesis Variable: Our variable for our experiment was the use of soap. In our controlled we had the use of soap and our independent variable was our second experiment having no soap. Our hypothesis was that without the use of soap the float per minute of the leaves would increase. Our predictions was that without the use of soap it would cause the leaves to form more air bubbles
because the liquid would no longer be a mixture of water with soap. In our controlled experiment only 6 of our leaves floated from the top of the cup and in our variable experiment we had all 10 of our leaves float. Both experiments were left overnight and the one experiment that did better was our controlled due to the floating of all our leaves. Calculation: For our first experiment with the soap the floats/min was 1 float every 14 minutes and 35 seconds. For our second experiment it was 1 float every 10 minutes and 22 seconds. Summary: The pre-lab questions help us understand the process of how the experiments work. It provides information on the stomata, other plant parts, and processes the leafs go through while the experiment is occuring. Overall the experiment helped me picture how fast and how slow oxygen can be made from a plant depending on the conditions of the plants environment. I know that in a good environment where there is a suitable balance of carbon dioxide and water a plant can go through photosynthesis and have a byproduct of oxygen.
