why only the green area of variegated leaf can produce starch by photosynthesis
Answers
Explanation:
The leaf on the left is a variegated leaf. The green parts contain chlorophyll and photosynthesise to make starch. ... This is evidence that chlorophyll is required for photosynthesis. A plant can be 'de-starched' by leaving it in the dark for a few hours.

Variegated leaves have areas that are white in color instead of being green. This is due to a lack of plastids that contain chlorophyll; without chlorophyll photosynthesis cannot take place. The areas of the leaves which are green produce monosaccharides through photosynthesis and this is stored as starch
