Question

The chief advantage of encystment to an Amoeba is:

• A. The ability to survive during adverse physical conditions
• B. The ability to live for some time without ingesting food
• C. Protection from parasites and predators
• D. The chance to get rid of accumulated waste products

Answer 1

The Correct Option is A

To address the given question regarding the chief advantage of encystment to an Amoeba, we need to understand what encystment is and its functions:

Encystment in Amoeba: Amoebas are unicellular organisms that can undergo a process called encystment. During unfavorable environmental conditions, such as extreme temperatures, dryness, or lack of food, an Amoeba can form a cyst around itself. This process involves secreting a tough protective membrane that encases the organism, allowing it to remain inactive inside the cyst.

Reasons for Encystment: The primary reason Amoebas undergo encystment is survival. Encystment allows the Amoeba to endure harsh conditions by going into a dormant state until the environment becomes favorable again. This ensures the organism's survival without needing to carry out normal metabolic activities.

Now, let's evaluate the given options:

• The ability to survive during adverse physical conditions: This option directly aligns with the primary purpose of encystment, which is to protect the Amoeba in harsh environments by becoming dormant.
• The ability to live for some time without ingesting food: While encystment does allow the Amoeba to survive without food, this is a consequence of dormancy rather than the chief advantage.
• Protection from parasites and predators: Although the cyst provides some level of protection, the main goal is not specifically defense against biotic threats.
• The chance to get rid of accumulated waste products: Encystment is not primarily for waste removal; it does not involve eliminating waste.

Conclusion: The correct answer is The ability to survive during adverse physical conditions. Encystment enables the Amoeba to withstand and live through periods where conditions are not suitable for active life.
