Question

Describe an activity to show that chlorophyll, carbon dioxide, light and temperature are neccescary for photosynthesis?

Answer 1

Answer:

Chlorophyll is necessary for photosynthesis:

The experiment to show that chlorophyll is necessary for photosynthesis is as follows a chlorophyll producing leaf along with the plant is taken and a chlorophyll bleached leaf along with the plant is taken.

Both these plants are destarched before the experiment and kept in the atmosphere containing water, carbon dioxide, and sunlight. After 24 hours the starch content of the leaf may be checked with an iodine solution to prove that the chlorophyll deprived plant did not produce any starch.
