Question

In an activity to prove that chlorophyll is essential for photosynthesis, what are the final observations? Please answer quickly!

Answer 1

Answer:

Observation : The blue colour appears only in those parts of leaf which were green in colour. ... This shows that starch formation takes place only in green (chlorophyll containing) parts of the leaf. Thus, the chlorophyll is essential for photosynthesis

Answer 2

Explanation:

In this experimental leaf, the part of the variegated leaf which contain green patches will give a positive test for starch i.e. iodine when added to this part of the leaf will turn into blue-black color. ... Thus this experiment proves chlorophyll is necessary for leaves to prepare starch through photosynthesis...
