Question 1: How does binary fission differ from multiple fission?
Answer:
Asexual reproduction occurs in different ways in different organisms. So, binary fission and multiple fission both are the types of asexual reproduction.
Binary fission:- It is the division of parent cell into two small daughter nucelii. Mainly three types of binary fission shown in some organisms- Irregular, longitudinal, transverse. Like in protozoan protists, the replicated chromosome separated by intranuclear mitosis and starts dividing. Then, the cytoplasm constricts between two separating nuclei and forms two equal sized daughter nuclei with a nucleus (eg. Amoeba shows irregular fission, Euglena shows longitudinal fission and Paramecium shows transverse binary fission). Or like in Planarians also, they are divided by transverse binary fission with the equal sized daughter individuals.
Multiple fission:- Unlike binary fission, the division of parent cell will be into many small daughter nuclei. And it can be shown in mainly two organisms- Plasmodium or Amoeba. Plasmodium is a malarial parasite, when multiple fission takes place in adults or in its encysted zygote (called sporogony) and their daughter individuals are then called merozoites.
