2. Amoeba :- It is binary fission . In which only one or two organism can reproduce .

Plasmodium :- It is a multiple fission in which two or more organism. can reproduce . ...

3. Fragmentation :- It is type of asexual reproduction in which multicellular organism break up into two or more fragments .

example ---- Algae.

Regeneration :- It is a type of asexual reproduction in which organism can reproduce
with there body part .

hope it help you
