The chief advantage of encystment of an Amoeba is:
the ability to survive during adverse physical conditions
the ability to live for some time without ingesting food
protection from parasites and predators
the chance to get rid of accumulated waste products
Solution
During adverse environmental periods, Amoeba survive by encystment by becoming circular, loses most of its water, and secretes a cyst membrane that serves as a protective covering. When the environment is again suitable, the envelope ruptures and the Amoeba emerges.
During unfavourable conditions, Amoeba undergo multiple fission inside the cyst to survive and reproduce under unfavourable conditions. In the multiple fission, the nucleus of the parent cell divides multiple times by amitosis (direct cell division), producing several nuclei. The cytoplasm, later on, separates, creating multiple daughter cells. When the conditions are unfavourable, Amoeba withdraws its pseudopodia and becomes almost round.
