Why is meiosis referred to as a process of cell reduction

Because in meiosis the number of chromosomes becomes half.

Explanation:

Meiosis is called reductional division because in meiosis the number of chromosomes gets half in daughter cells after cell division.

Meiosis takes place in gametic cells. In meiosis four haploid cells are produced from one diploid mother cells. Two cell division takes place in meiosis. During the first cell division, the chromosome number gets half due to the separation of a homologous chromosome which makes the daughter cell haploid.

Therefore as chromosome number in daughter cell becomes half so meiosis is referred to as a process of cell reduction.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
