Give hypotheses for oxygen production and usage during each of photosynthesis and respiration. (4 pts)
-
photosynthesis
-
respiration
-
-
Based on these hypotheses, predict when (e.g. during “day” and/or “night”) the bubble will move toward or away from the test tube in each experiment. (2 pts)
-
How far (in mm) did the bubble move during the “daytime” (photosynthesis and respiration)? How far (in mm) did the bubble move during the “night” (respiration only)?
photosynthesis + respiration ("day") respiration only ("night") initial final distance moved (use + or -) If the Elodea had not been respiring during photosynthesis, how far would the edge have moved? (Tell exactly how far, i.e., a number with \(+\) or \(-\).) Please show your math! (5 pts)
-
Why exactly do plants carry out photosynthesis? When do plants photosynthesize (day, night)? (2 pts)
-
Why exactly do plants carry out respiration? When do plans respire (day, night)? (2 pts)
