Question

Read the assertion and reason carefully to mark the correct option in question.

Assertion: Leaf is a lateral outgrowth of stem developed exogenously at the node.

Reason: The floral characteristics form the basis of classification and identification of flowering plants.

• A. If both assertion and reason are true but reason is not the correct explanation of the assertion.
• B. If both assertion and reason are true and the reason is the correct explanation of the assertion.
• C. If assertion is true but reason is false.
• D. If both assertion and reason are false.

Answer 1

The correct option is A If both assertion and reason are true but reason is not the correct explanation of the assertion.

Leaves are dorsoventrally flattened parts of plants which are lateral outgrowths emerging from the nodes. They are the main structures of the plants responsible for conducting photosynthesis. Hence, the given assertion statement is correct.

With the help of floral characteristics, flowering plants can be classified into different groups known as families. Floral characteristics of different families are summarised in a scientific manner with the help of floral formula and floral diagrams.

Hence, the reason statement is also correct, however, not the correct justification of the assertion.
