what is fission? and types of fission
Answers
Explanation:
BINARY FISSION - DEFINITION
The type of asexual reproduction in which a microorganism splits in two equal halves is called as binary fission, e.g., Amoeba.
The cells which split during binary fission have the potential to grow to the size of the original one.
There are two types of binary fission: transverse (e.g., Paramoecium) and longitudinal (e.g., Euglena).
MULTIPLE FISSION - DEFINITION
In some prokaryotic organisms binary fission occurs in a very unique way which includes dividing into many daughter cells simultaneously by the means of multiple fission.
Amoeba withdraws its pseudopodia and secrets a hard covering around itself, which is called as cyst formation. When the conditions are unfavourable for Amoeba the nucleus divides into many daughter nuclei. As the cytoplasm divides it gives rise to many daughter cells.
During favourable conditions the cyst breaks open and releases many daughter cells.
Answer:
Fission is a mode of asexual reproduction in which the unicellular parent (organisms) divide into two or more than two daughter cells (offsprings).
It is of two types :
(i) Binary fission- two equal daughter cells are produced.
Eg: Amoeba
(ii) Multiple fission- more than two daughter cells are produced.
Eg: Plasmodium
