Assertion(A): If C O 2 is increasing continuously, there will be an increase in photosynthesis.
Reason (R): C O 2 is the main substrate of photosynthesis.
  • a)
    Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
  • b)
    Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

Although CO2 is a main substrate of photosynthesis and an increase in CO2 will cause an increase in photosynthesis to a certain amount after a point due to other limiting factors such as light intensity or presence of water this increase will stop. Therefore reason is true but assertion is false.

In the following question, a Statement of Assertion (A) is given follo...
Understanding the Assertion and Reason
The Assertion (A) states that if carbon dioxide (CO2) is continuously increasing, photosynthesis will also increase. The Reason (R) claims that CO2 is the primary substrate for photosynthesis.
Analysis of the Assertion
- Assertion (A): This is not entirely accurate. While CO2 is a crucial component for photosynthesis, the increase in CO2 alone does not guarantee an increase in photosynthesis. Other factors such as light intensity, temperature, and water availability also play significant roles. Thus, the assertion is considered false.
Analysis of the Reason
- Reason (R): This statement is true. CO2 is indeed the main substrate for photosynthesis, as plants use it during the process to produce glucose and oxygen.
Conclusion
- Since the assertion is false and the reason is true, the correct answer is option 'C': "Assertion is false but Reason is true."
Key Points Summary
- Assertion (A): False - CO2 increase does not necessarily lead to increased photosynthesis.
- Reason (R): True - CO2 is essential for the photosynthesis process.
- Final Answer: Option 'C' is the correct choice as it accurately reflects the truth of both statements.
