starch present / starch not present (table)

Starch present in A and C, starch not present in B.

Explanation:

Photosynthesis is the process by which plants synthesise sugar.

This process requires light energy, carbon dioxide, and water, and produces sugar and oxygen. This sugar can be turned into starch.

In leaf B, the chemical that absorbs carbon dioxide would mean that there is none in the air for the plant to take in and use for photosynthesis, so it would not make sugar which can be converted to starch.

This is in contrast to C and A, where there is carbon dioxide present in the bag that can be used in photosynthesis.
