Life Processes in Plants Class 7 Assertion-Reason Type Questions
Assertion-Reason Questions
Directions: Each of the questions (i) and (ii) contain two statements – first Assertion’ and second ‘Reason’. Select the correct answer to these questions from the codes (a), (b), (c) or (d) as given below:
(a) Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
(b) Both Assertion and Reason are true and Reason is NOT the correct explanation of Assertion.
(c) Assertion is true and Reason is false.
(d) Assertion is false and Reason is true.
(i) Assertion (A): Roots are involved in photosynthesis.
Reason (R): Photosynthesis takes place only in green parts of plants.
Answer:
(d) Assertion is false and Reason is true.
Explanation:
Roots are not green and do not perform photosynthesis.
(ii) Assertion (A): Leaves are called the food factories of plants.
Reason (R): Leaves contain chlorophyll, which helps in the process of photosynthesis.
Answer:
(a) Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
Explanation:
Leaves are called the food factories of plants because they are the primary sites where food is produced. The green pigment chlorophyll present in leaves absorbs sunlight, which provides the energy needed for photosynthesis.
