Question

8 Why is it important that a plant should be destarched before it is used in photosynthesis investigations?​

Answer 1

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

Answer 2

Answer:

Hope you find this helpful :)

Explanation:

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.

All plants have starch in their green leaves. ... During this period, the plant cannot make more starch by photosynthesis as there is no sunlight and will use up all the starch stored in its leaves. This destarched plant can then be used in photosynthesis experiments to obtain accurate results.
