Question

3. If you are planning an experiment to show the
effect of light on photosynthesis :
(a) Will you select white light or green light?Justify your answer.
(b) Why would you select a destarched plant?​

Answer 1

Answer:

a) green light because it will reflect back n if we take white light it will be absorbed .

b) we destarch plant to show that light is necessary for plants

Answer 2

Answer:

(a) I will select white light because photosynthesis is maximum in white light while it is minimum in green light as green light is reflected by green plants.

(b)It is necessary to destarch a plant before performing photosynthesis experiment because the amount of starch formed during the experiment should be validated. I will select destarched plant so that I can demonstrate the synthesis of starch through iodine test.
