Question

Explain why some parts of the leaf contain starch and others do not.​

Answer 1

Answer:

Excess energy, created from photosynthesis, is stored in plant tissue as starch. ... It houses glucose, which plants use for food. The presence of starch in a leaf is reliable evidence of photosynthesis. That's because starch formation requires photosynthesis.

Answer 2

Answer:

The green parts contain chlorophyll and photosynthesis to make starch. The white part of the leaf does not contain chlorophyll, so does not photosynthesis.

Explanation:

Starch is stored in the stroma of the chloroplasts and in the cytoplasm of leaves.
