Diploid cell
Diploid Cell
A Diploid Cell (/dɪˈplɔɪd/ cell) is a cell that contains two complete sets of chromosomes, one from each parent. The term "diploid" comes from the Greek words "di", meaning "two", and "ploos", meaning "fold".
Etymology
The term "diploid" was first used in the late 19th century and is derived from the Greek words "di", meaning "two", and "ploos", meaning "fold". This refers to the fact that diploid cells contain two complete sets of chromosomes.
Definition
In Genetics, a Diploid Cell is a cell or organism that has paired chromosomes, one from each parent. In a diploid state, the haploid number is doubled, thus, this condition provides a species with a relative amount of stability in its genetic makeup.

- Polyploid: A cell or organism that contains more than two copies of each of its chromosomes. Polyploidy is common in plants.
- Chromosome: A thread-like structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
- Genome: The complete set of genes or genetic material present in a cell or organism.
- Mitosis: A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
- Meiosis: A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
