What is an abbreviation for a diploid cell?

2n

What is a zygote?

The diploid cell that results from the fertilization between an egg and a sperm.

What is a haploid number?

The number of chromosomes in a gamete after meiosis. It is half the number of chromosomes in a diploid number.

What is a diploid number?

The number of chromosomes in a somatic cell. It is twice the number of chromosomes in a sex cell.

What is a gamete?

A cell that fuses with another cell during fertilization in organisms that reproduce sexually. Also known as "sex cells" or "germ cells".

What is fertilization?

Also known as "conception". A process in sexual reproduction that involves the union of male and female gametes (each with a single, haploid set of chromosomes) to produce a diploid zygote.

What is a somatic cell?

Any cell other than a gamete.

What is a haploid cell?

Cells containing half the number of chromosomes as a diploid cell. These are sex cells-- upon fertilization the newly-formed zygote will be diploid-- inheriting one set of chromosomes from each parent.

What is a diploid cell?

Cells containing two complete sets of chromosomes, one inherited from each parent.

What is an example of a haploid cell?

Gamete.

Why do haploid cells have half the number of chromosomes as diploid cells?

Haploid cells are sex cells. They contain half the number of chromosomes as diploid cells, because they unite with another haploid sex cell during fertilization. This union of two haploid sex cells during fertilization ensures that the resulting zygote is diploid-- having inherited one set of chromosomes from each parent.

What are the major differences between haploid cells and diploid cells?

Haploid cells have one set of chromosomes and are formed by meiosis. Diploid cells contain two sets of chromosomes and are formed by mitosis.

What is an example of a diploid cell?

Somatic Cell.
