Questions and Answers

What is the significance of the green part of a variegated leaf in the context of the iodine starch test?

The green part of the leaf turns iodine from brown to blue-black, indicating the presence of starch.

How does the presence of chlorophyll affect the ability of a leaf to carry out photosynthesis?

Chlorophyll enables the leaf to carry out photosynthesis.

Why does the yellow part of a variegated leaf test negative for starch?

The yellow part lacks chlorophyll, so it cannot carry out photosynthesis to form starch.

Explain why the green part of a variegated leaf is used as a control in experiments related to photosynthesis.

The green part serves as a control because it has all the necessary conditions for photosynthesis to occur. Signup and view all the answers
