Experiment on Preparing Stomata, Photosynthesis and Cellular Respiration
The students prepared a wet mount of scallion stomata, photosynthesis of Elodea plant using Bromthymol Blue indicator and Cellular Respiration using yeast cell in pipette.
Bromthymol blue changes color from blue to yellow when CO2 is blown into and changes back to blue when Elodea was put inside and let it photosynthesize under the sun.
To end the chapter, the students presented a role play on photosynthesis and cellular respiration.

Good job guys!!! |

Comparison of Elodea under the sun and in dark. The one under the sun changes the color of Bromthymol blue back to blue and one in the dark still remained yellow.

The group planned to show this nice video about cellular respiration but they didn't get the chance. |
