Assertion Reason Questions on Life Processes in Plants
Assertion Reason Questions
Q1. Assertion (A): Chlorophyll present in the leaves captures sunlight for photosynthesis.
Reason (R): Chlorophyll absorbs carbon dioxide directly from the soil for food preparation.
Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (c) A is true, but R is false.
Explanation: Chlorophyll captures sunlight, but carbon dioxide is absorbed from the air, not from the soil.
Difficulty Level: Moderate
Q2. Assertion (A): Stomata help plants in the exchange of gases necessary for photosynthesis and respiration.
Reason (R): Stomata are found only on the stems of plants.
Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (c) A is true, but R is false.
Explanation: Stomata are mainly present on the surface of leaves, not stems.
Difficulty Level: Moderate
Q3. Assertion (A): The process of photosynthesis releases oxygen into the environment.
Reason (R): Oxygen is a waste product for plants and is not useful in any biological process.
Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (c) A is true, but R is false.
Explanation: Oxygen is essential for respiration in plants, animals, and humans.
Difficulty Level: Moderate to Tough
Q4. Assertion (A): Xylem is responsible for the transport of food from leaves to other parts of the plant.
Reason (R): Xylem transports water and minerals absorbed by the roots to other parts of the plant.
Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (c) A is false, but R is true.
Explanation: Xylem transports water and minerals; food is transported by phloem.
Difficulty Level: Tough
Q5. Assertion (A): Plants respire to release energy required for their growth and maintenance.
Reason (R): During respiration, plants absorb oxygen and release carbon dioxide.
Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (a) Both A and R are true, and R is the correct explanation of A.
Explanation: Respiration provides energy for plants, with oxygen intake and carbon dioxide release as part of the process.
Difficulty Level: Moderate

Frequently Asked Questions (FAQs) on Life Processes in Plants Assertion Reason Questions
Q1: What are Assertion-Reason questions in Class 7 Science?
A1: Assertion-Reason questions consist of two statements: an Assertion (A) and a Reason (R). Students must determine whether both statements are true and if the reason correctly explains the assertion.
Q2: How do I answer Assertion-Reason questions correctly?
A2: To answer correctly, follow these steps:
Check if both statements are true.
If both are true, see if the reason logically explains the assertion.
Use the standard answer choices (Both true with explanation, Both true without explanation, A true but R false, A false but R true).
Q3: What is the new Science textbook “Curiosity” for Grade 7 about?
A3: The new textbook “Curiosity” for Grade 7 Science introduces students to the world of scientific exploration and discovery.
