Assertion: During favourable conditions, Amoeba undergoes encystment.
Reason: During unfavourable conditions, it produces Amoebulae.
Answer:
The given assertion and reason are related to the life cycle of Amoeba. Let's evaluate the given statement:
Encystment in Amoeba:
- Encystment is a protective mechanism exhibited by certain organisms, including Amoeba, during unfavorable conditions.
- When the environmental conditions become unfavorable, such as scarcity of food, extreme temperatures, or lack of moisture, Amoeba forms a protective cyst around itself.
- The cyst is a dormant stage where the Amoeba becomes rounded and surrounded by a thick, resistant cyst wall.
- Encystment helps Amoeba to survive harsh conditions and wait until the environment becomes favorable again.
Amoebulae Production in Amoeba:
- The process of encystment in Amoeba is followed by the production of amoebulae, which are small, flagellated cells.
- Amoebulae are formed within the cyst and are released when the conditions become favorable again.
- These amoebulae are highly active and possess flagella, which helps them in dispersal and finding a suitable environment.
- Once the amoebulae find favorable conditions, they settle and develop into full-grown Amoeba.
Evaluation of the Assertion and Reason:
- The assertion states that Amoeba undergoes encystment during favorable conditions, which is incorrect.
- The reason states that Amoeba produces amoebulae during unfavorable conditions, which is also incorrect.
- Both the assertion and reason are false.
Conclusion:
Based on the evaluation, we can conclude that option (D) Both A and R are false is the correct answer.
Reason: During unfavourable conditions, it produces Amoebulae.
