Your group will use sprigs (pieces) of Elodea, a water plant. The bromthymol blue will not interfere with respiration or photosynthesis in Elodea. You have test tubes and corks at your disposal, as well as other materials, including aluminum foil (which is an excellent way to provide a plant with a totally dark environment). You may use as many ...

3 2. Elodea Experiments Experiment 1: Elodea in the Light Fill one of two flasks with 250 ml of tap water and add 10 drops of phenol red. Make the water in the flask slightly acidic by gently breathing into the flask while swirling it. Repeat if necessary to get a slight color change from neutrality, but do not make the solution too acidic (yellow).

In our experiment, we are going to determine the rate of photosynthesis by measuring oxygen production of a water plant, elodea under bright light, different colors of light and dim light. We are going to use two different method in measuring the oxygen production. The first method is to count the oxygen bubbles prodused in a given time. Second ...

algae Elodea. We did this by using a Gilson Respirometer and samples of Elodea plant placed in H2O and NaHCO 3 solutions—both of which were operated under lighte d and darkened external conditions—to measure the consumption of CO 2 during photosynthesis and the production of CO 2 during respiration.

Photosynthesis and Respiration in Elodea Experimental Design Sheet Restate the two tasks of your experiment as hypotheses. Task A - Task B - Draw the design of your experiment. Include "controls" in your design. Also include: 1. the test tubes 2. whether there is a plant in the test tubes or not 3. the starting colour of the bromthymol blue ...

• When you receive your Elodea, remove it from the packaging and gently rinse away any debris or broken off pieces. • Your Elodea is a freshwater organism that should be kept in de-chlorinated water. Water from the tap in most homes contains chlorine which can be detrimental to the health of your aquatic plant. Elodea should be fully sub-

dependent reactions of photosynthesis cannot take place due to the lack of light. Therefore, the shift is due to the plant's respiratory processes only. • By comparing tubes “B” and “F,” it can be seen that while the bromthymol blue itself may have tended to acidify slightly, the tube with the Elodea (going through the respiratory ...

You have learned that photosynthesis involves the conversion of carbon dioxide and water into organic molecules such as glucose. In doing so, oxygen is a product while carbon dioxide is a reactant that is used up during photosynthesis. In the first experiment, we will be using the same plant you examined in Lab 3 called Elodea. The experimental ...
