BUDDING IN HYDRA: AN out growth is observed in the body of hydra.Protuberance is large enough and is multicellular.But they appear detaching.Bud bears separate mouth and tentacles.
BUDDING IN YEAST: A small protuberance grows on the upper part of yeast cell.Nucleus divides automatically.Newly divided nucleus moves to bud.Repeated budding form the chain of cells.
BINARY FISSION IN AMOEBA: parent cell becomes elongated.Nuclear body elongates and gets ready to split. At point of fission cleavage or ferrow can be observed. Two daughter cells are formed.
Binary fission is a method of sexual reproduction especially in protozoans.Binary means 2 and fission means to split.In binary fission a living organisms divides into 2. eg: bacteria,amoeba, paramezium etc
