Reserve food in the cystic form of Entamoeba histolytica is in the form of

Explanation

The trophozoite undergo binary fissions in the wall of the large intestine and produce a number of daughter entamoebae. They feed upon the bacteria and the hostly tissue elements, grow in size and" again multiply. After repeated binary fissions some of young ones enter the lumen of the large intestine and transform into precystic stage. Here, the precystic stage transforms into cystic stage. Which inturn develope into tetranucleate cyst. The entire process is completed only in a few hours. These tetra nucleated cysts Pseudopodium come out along with the faecal matter and can remain alive Endoplasm for about 10 days. These cysts reach new hosts through --Ribosome contaminated food and water. They pass into the small - Food vacuole intestine of a new human host. Where the cyst wall get, with bacterium ruptured by the action of enzyme of trypsin releasing tetra Nucleolus Cartwheel nucleated amoeba. Such tetra nucleated excyst amoeba are shaped nucleus called metacyst. The four nuclei of the metacyst undergo - Food vacuole with RBC mitotic divisions and produce eight núclei. Each nucleus gets Ectoplasm a bit of cytoplasm and thus eight daughter entamoebae are produced. The young ones develop into trophozoites and Trophozoite Stage invade the large intestine.
