Algae Bead Photosynthesis Lab. Web in this lab, students observe photosynthesis through changes in the color of an indicator solution. The photosynthesis and cellular respiration kit for ap biology is a fun, easy to use, and more reliable alternative to the leaf disk and microrespirometer labs.

Web this experiment aims to observe the effects of the variable distance from a lightbulb (variable light intensity) on the rates of algal photosynthesis. Web percent algae coverage measurements were performed according to standard operating procedures (sop) provided by wvdep. When algae consume carbon dioxide during photosynthesis, the ph of the solution increases. Web algae and plants perform both photosynthesis and respiration. We will add later during class independent variable: Observe algae beads for evidence of photosynthesis. Gives off/releases co2 into solution Add 2.5 ml of 2% sodium alginate solution to the tube, place the cap on the tube, and mix for 1 to 2 minutes. The culture should be dark green. Photosynthesis, the process by which green plants convert light energy into chemical energy, is dependent upon the input of solar radiation.
After 24 hours, what color will the bicarbonate indicator become if photosynthesis is occurring at a greater rate than algal respiration? Web teach both photosynthesis and cellular respiration simultaneously in a single lab. As the algae photosynthesize, they will change their solution’s ph as they draw in carbon dioxide. Classes, camps, birthday parties, field trips and more! Due to the equipment available, length was recorded in meters and depths in inches. Add 2.5 ml of 2% sodium alginate solution to the tube, place the cap on the tube, and mix for 1 to 2 minutes. Create green algae spheres for use in photosynthesis experiments. Lower co2 in solution = higher ph (more basic) (purple) cell respiration: In experiment 2, students specifically look at light color to determine which wavelength of light increases the rate of photosynthesis. We will add later during class independent variable: The photosynthesis and cellular respiration kit for ap biology is a fun, easy to use, and more reliable alternative to the leaf disk and microrespirometer labs.
