Definition

A type of cell division that occurs in sexually reproducing organisms, which reduces the chromosome number in reproductive cells, resulting in the formation of gametes or spores.

Example

Meiosis is essential for sexual reproduction as it produces gametes with half the number of chromosomes.

Conversation

Have you ever heard of meiosis in biology?

Yeah, I've come across it; it's about how cells divide, right?

Exactly! It’s the process that reduces chromosome numbers for gametes.

Right, it's fascinating how that leads to genetic diversity.

Synonyms & Antonyms

Root Explanation

Meiosis → It is formed from "meioun" (Greek, meaning to lessen) and the suffix "-sis" (meaning process or action). The term describes the process of cell division that reduces the chromosome number, hence 'lessening' the genetic material.

Memory Tip

Think of 'lessening' ('meioun') the number of chromosomes during cell division — that's what meiosis means.
