We know that organisms show binary fission under favourable conditions and under unfavourable conditions they show multiple fission . Do organisms show multiple fission only under unfavourable conditions ?? is there any organism which show multiple fission during favourable conditions ??

Solution

Dear student.

Not all organism shows multiple fission only in case of unfavourable condition. There are many organisms such as Plasmodium, Chlamydomonas, algae reproduce by multiple fission in a normal condition. Organism such as Amoeba shows multiple fission in an unfavourable condition, in favourable condition, they reproduce by binary fission. Unfavourable conditions include temperature, humidity, dryness etc. Predators may also impact the amoeba.
