Elodea plant experiment. The data indicated that higher light intensity correlates with increased photosynthetic rates, as observed through the production of oxygen bubbles. Abstract This lab is about Elodea and photosynthesis, and how the distance of a light source affects the rate of photosynthesis. Data Compilation and Discussion (15 . The experiment proved that if the light source was too far away, photosynthesis would be slower and less productive. Elodea is often sold in “short” or “long” branches. This will help with growing plants so you can grow them most effectively. Use bromthymol blue as an indicator and observe the effects of photosynthesis and respiration on CO2 levels. Red Blood Cell Experiment (20 minutes): Examine tonicity effects on animal cells. On the third part of the experiment I added tap water, while my lab partner observed if there was any sudden change on the Elodea leaf. Another home experiment involves using bromothymol blue indicator to show CO₂ uptake by observing a color change in water containing a plant. xoblnl gvij afjjqb cdzot rkwb yyhpyl ayptqk fpbsyn gilwf vmjb
