Binary Fission
Binary fission is a type of asexual reproduction in which one cell divides into two daughter cells.
Practice This ConceptMain explanation
Teacher explanation
In binary fission, the parent cell first copies its genetic material and then splits into two nearly equal parts. This is a fast and efficient method in simple unicellular organisms. Amoeba and bacteria are common examples taught at Class 10 level.
Example
Amoeba divides into two daughter cells by binary fission when conditions are favourable.
Simple analogy
Binary means two, so one cell becomes two.
Common confusion
Students sometimes think the parent cell simply vanishes before offspring form. In reality, the cell divides into two living daughter cells.
Exam tip
Remember the word binary, which means two. It helps you recall that one parent cell forms two daughter cells.
