action spectrum

• what is an action spectrum


  this is a graph that shows the rate of photosynthesis at different wavelengths of light
• suggest a simple experiment that would measure the rate of photosynthesis


  count the number of bubble produced by a pond weed in one minuet
• describe the relationship between the graph for the absorption spectrum and the action spectrum


  the close correlation suggests that the pigments that absorb light energy are responsible for photosynthesisSee an expert-written answer!We have an expert-written solution to this problem!
• What was Engelmann's experiment?


  he places the algae in a suspension of motile , aerobic bacteria and he exposed the algal cells to a range of wavelengths
• what type of chloroplasts were used in engelmanns experiment


  spiral chloroplasts
