Question

explain the different methods of the following asexual reproduction a) fission - two types? cbse class10 biology

Answer 1

Answer:

There are several different methods of asexual reproduction. They include binary fission, fragmentation, and budding. Binary fission occurs when a parent cell splits into two identical daughter cells of the same size.

Binary fission ("division in half") is a kind of asexual reproduction. It is the most common form of reproduction in prokaryotes such as bacteria. It occurs in some single-celled Eukaryotes like the Amoeba and the Paramoecium. ... During binary fission, the DNA molecule divides and forms two DNA molecules.

Binary Fission in Bacteria

Step 1- Replication of DNA. The bacterium uncoils and replicates its chromosome, essentially doubling its content.

Step 2- Growth of a Cell. After copying the chromosome, the bacterium starts to grow larger in preparation for binary fissions. ...

Step 3-Segregation of DNA. ...

Step 4- Splitting of Cells.

Answer 2

Answer:

Fission are of two types

1. Binary Fission:- Two daughter cells are formed

e.g. Amoeba , Bacteria

2. Multiple fission :- Many daughter cells are formed

e.g. Plasmodium, Chlamydomonas, algae
