Cell Division
Cell division is the process by which a parent cell divides to form new cells, mainly through mitosis or meiosis.
Practice This ConceptMain explanation
Teacher explanation
Mitosis produces two identical daughter cells with the same chromosome number and is used for growth, repair, and replacement. Meiosis produces gametes with half the chromosome number, helping maintain chromosome number across generations after fertilisation.
Example
Skin cells divide by mitosis for repair, while reproductive organs form gametes by meiosis.
Simple analogy
Mitosis maintains; meiosis makes gametes.
Common confusion
Students often write that meiosis produces two identical cells, but meiosis produces four genetically different gametes with half the chromosome number.
Exam tip
In comparison questions, always write number of daughter cells, chromosome number, and purpose.
