Explain encystment in amoeba.

Explanation

(i) During unfavourable conditionis Amoeba withdraws its pseudopodia and secretes a three -layered, protective, chitinous cyst wall around it becomes inactive. This phenomenon is called encystment.
(ii) When conditions become favourable, the encysted Amoeba divides by multiple fission and produces many minute amoebae called pseudopodiospore or amoebulae.
(iii) The cyst wall breaks off liberating the young pseudopodiospores.
