Question

Why is it necessary to destarch a plant before performing any experiment on photosynthesis?
​

Answer 1

$\huge{\mathfrak{\underline{\underline{Answer :}}}}$

It is important to destarch a plant before performing any experiment on photosynthesis so that it can be established whether or not a particular factor (carbon dioxide/ light/ water) is important for the photosynthetic reaction. Incase, the starch is already present in the leaves, it may lead to an erroneous interpretation.

Answer 2

It is necessary to destarch a plant before performing photosynthesis experiment because the amount of starch formed during the experiment should be validated. Plants produce starch through an important process called photosynthesis with the help of the chlorophyll pigment that is present in the leaves.
