Hi friend
here is your answer
An amoeba reproduces asexually by a process called binary fission.
It pulls its pseudopodia to attain a spherical shape.
Mitotic cell division takes place, which constricts the nucleus and cytoplasm and forms two daughter cells. Thus, the genetic information in the nucleus is copied in both the cells which makes them identical.The free amoebae are called trophozoites. Binary fission in amoebae lasts around 30 - 60 minutes under ideal conditions.
Amoeba can also reproduce by a process called multiple fission. It usually applies this process under abnormal circumstances, wherein the environment lacks the necessary nutrients.
In multiple fission Amoeba retracts its pseudopodia and attains a more spherical shape. In dangerous situations, where natural conditions make survival difficult for the amoeba, it forms a protective covering, around itself to form a cyst. This cyst is able to survive harsh and rough conditions which are potentially harmful for a normal amoeba.
Inside the cyst, multiple mitosis takes place. This process produces many daughter cells inside the cyst, which are protected against the unsuitable environment. Once favourable conditions are back the cyst ruptures and daughter amoebae are released from it.
if u have any questions about this topic,
please concern with me
may this helps you

________________
Life Cycle. Cysts and trophozoites are passed in feces (1). ... Infection byEntamoeba histolytica occurs by ingestion of mature cysts (2) in fecally contaminated food, water, or hands. Excystation (3) occurs in the small intestine and trophozoites (4) are released, which migrate to the large intestine.
