Diploid cell

Diploid cell is a cell or organism that has paired chromosomes, one from each parent. In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes. Diploid cells reproduce by mitosis making daughter cells that are exact replicas.

Overview

A diploid cell is a cell that contains two sets of chromosomes. This is double the haploid chromosome number. In humans, the diploid number of chromosomes is 46 (2n=46), while the haploid number is 23 (n=23).

Diploid Cells in Humans

In humans, every cell except for sperm in males and eggs in females are diploid cells. These cells contain 23 pairs of chromosomes, for a total of 46. Each pair of chromosomes contains one chromosome from the mother and one from the father.

Reproduction of Diploid Cells

Diploid cells reproduce using a process called mitosis, where the cell divides into two, producing two identical daughter cells. This is different from the process of meiosis, which is used by haploid cells to reproduce and results in four non-identical daughter cells.

Importance of Diploid Cells

Diploid cells are important for the survival of most organisms, as they allow for genetic diversity. The pairing of chromosomes allows for the recombination of genes, which leads to variations in traits. This genetic diversity is crucial for the survival and evolution of species.
