Read the following statements and choose the correct option: Assertion: Presence of starch in leaves indicates the occurrence of photosynthesis. Reason: Carbohydrate formed during photosynthesis ultimately gets converted to starch.
Both assertion and reason are correct and reason is the correct explanation of the assertion
The assertion is correct: leaves are tested for starch, using the iodine test after destarching, precisely because the presence of starch confirms that photosynthesis has taken place in that leaf.
The reason is also correct: during photosynthesis, plants first make simple carbohydrates, and this carbohydrate is subsequently converted into starch, which is stored in the leaf cells.
Since the conversion of photosynthetic carbohydrate into starch is exactly why starch presence indicates that photosynthesis occurred, the reason correctly explains the assertion.
Hence, the answer is that both the assertion and reason are correct, and the reason is the correct explanation of the assertion.
