Two statements are given – one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer from the codes given below: Assertion (A): CO2 incubators prevent the desiccation of the animal cell culture medium. Reason (R): A pan of water is kept at all times in a CO2 incubator chamber to maintain high relative humidity.
Show Hint
CO2 incubators maintain humidity using a water pan to keep cell culture medium hydrated and viable.
Both Assertion (A) and Reason (R) are true and the Reason (R) is the correct explanation of the Assertion (A).
Both Assertion (A) and Reason (R) are true, but the Reason (R) is not the correct explanation of the Assertion (A).
Assertion (A) is true, but Reason (R) is false.
Assertion (A) is false, but Reason (R) is true.
Show Solution
The Correct Option isA
Solution and Explanation
CO2 incubators are engineered to optimize conditions for animal cell cultures. This involves maintaining high humidity to avert desiccation of the culture medium. A water pan within the incubator is crucial for sustaining this humidity, thereby inhibiting medium evaporation.
Assertion (A): Correct. Preventing desiccation is critical for the viability of cell cultures.
Reason (R): Correct. The water pan ensures the necessary humidity levels.
The provided Reason accurately supports the Assertion, indicating option (A) as the correct choice.
