Question

How does binary fission differ from multiple fission? ​

Answer 1

Answer:

Binary fission

• 2 daughter cells are formed from the splitting of the parent’s cell or Nucleus.
• Occurs during favourable conditions.
• Divides only once.
• Both the Nucleus and cytoplasm divide simultaneously.
• Includes definite pattern of division.
• Example: Amoeba, Bacteria, Euglena, etc.,

Multiple fission

• Many daughter cells are formed from the splitting of the parent’s cell or Nucleus.
• Occurs during unfavourable conditions.
• Divides repeatedly.
• First, the nucleus divides and is surrounded by cytoplasm.
• Has no definite pattern of division.
• Example: Plasmodium, Sporozoans, Algae, etc.

Answer 2

Binary fission involves the cell division of an organism(eg. amoeba) to form two daughter cells.

It is the normal form of asexual reproduction in unicellular organisms such as amoeba, paramecium ,etc.

Multiple fission takes place in unicellular organisms such as amoeba, when moisture is not available or when extreme conditions of temperature are there, then the organism withdraws its protoplasm and pseudopodia, forms a membraned cyst around itself, inside, repeated divisions of organelles, nuclei and cytoplasm takes place, when moisture and other conditions become available again, the cyst opens to release many daughter cells with some cytoplasm around them.
