Question

What is Cyst?and amoebulae

Answer 1

Cyst is a Hard covering formed around an amoeba during unfavourable conditions.

When amoeba does reproduction in such conditions, it is known as Multiple fission.

In multiple fission, amoeba goes under nuclear divisions and forms several daughter nuclei.
But, cytoplasmic division does not take place.

On the arival of favourable conditions, the cyst breaks and and these daughter nuclei get released out of the cyst, these are known as amoebulae.
