12. A group of students studied the effect of light intensity on the rate of a cell process in Elodea plants. The students exposed Elodea plants to different light intensities. A gas was produced by the cell process. The amount of this gas was measured. The rate of the cell process was determined by the amount of gas produced.

Because oxygen is only slightly soluble in water, aquatic plants such as Elodea give off visible bubbles of oxygen as they carry out photosynthesis. By measuring the rate at which bubbles form, you can measure the rate of photosynthesis. Hypothesis: Write a hypothesis concerning the relationship between light intensity and the rate of ...

Place one test tube under bright light or a reflector lamp, the second test tube in day light, the third in diffuse light, and the fourth in total darkness. After about 15 minutes, observe the cut ends of each plant. Count the number of oxygen bubbles given off by each plant in one minute. Then count the number of bubbles in five minutes.

Photosynthesis in Elodea. In an intact plant, both electron transport and carbon fixation will continue as long as the plant is illuminated, and it is possible to study the effect of light intensity and the concentration of CO2 on the rate of photosynthesis.

Cut the end of the sprig of Elodea. GENTLY crush the freshly cut end. Place the Elodea in the Graduated Cylinder or test tube. Be sure the freshly cut end of the Elodea is toward the top of the tube or cylinder. Start Here: In groups of two or three(1 recorder/Timer, 1 Observer, 1 Marker) Now place the Elodea in front of the light and turn it on.

Purpose: To determine how light intensity impacts photosynthesis rates. Procedure: Move the light source to 100mm distance from the elodea plant. Hit the start button. When the experiment begins you will hit the tap button for each new bubble created by the elodea. When you feel that you have sufficiently timed the tapping to the bubble ...

11. Measure the light intensity at this distance using the light meter or calculate the. light intensity by using the formula: light intensity = 1/d2, where ‘d’ represents the . distance.from the light source. Record result. 12. Repeat the procedure from step 9 at other measured distances e.g. at 30 cm, 45 cm, 60 cm, 75 cm. 13.
