them in hydrogencarbonate indicator solution. As the algae photosynthesise, they take in carbon dioxide which causes the pH around them to increase. The indicator changes from orange, through red to magenta. Whichever technique is used, you should

The colour of the hydrogen-carbonate indicator solution remained orange. Explanation Guaze partially allows the light to enter the test tube. Therefore, the rate of respiration equals the rate of photosynthesis. So, there is no change in CO 2 in the test tube, which
Effect of light intensity on photosynthesis, using …
A2 Biology: I really need help with this question at college! “Design an investigation, using hydrogencarbonate indicator solution, to study the effect of light intensity or wavelength on the rate of photosynthesis in Spirogyra” Okay well incase you didn’t know already

· PDF 檔案photosynthesis is greater than the rate of respiration so more carbon dioxide is taken up by the plant than is released in respiration. The low CO 2 level makes the hydrogen carbonate indicator purple.
