Question

Why are sperm and egg haploid cells?

Answer 1

Hint: The reproductive cells of an organism are called gametes. Sex cells are another name for them. Male gametes are known as sperm, whereas female gametes are known as ova or egg cells. Gametes are haploid cells with only one copy of each chromosome in each cell.

Complete answer:
The sperm and egg combine to form a zygote. The zygote will go through various stages of development and growth before becoming an individual of a species.

In a species, the number of chromosomes must remain consistent. Gamete cells go through meiosis to keep the number of chromosomes in a species constant. Because it reduces the number of chromosomes, meiosis is known as the reduction division. It only occurs in diploid cells and converts them to haploid cells (n), such as gamete cells.

Both gametes will have half the number of chromosomes after meiosis, and when fusion happens, the original chromosome number will be restored, guaranteeing that the number of chromosomes in a species remains constant.

The reproductive cells of an organism are called gametes. Sex cells are another name for them. Male gametes are known as sperm, whereas female gametes are known as ova or egg cells. Gametes are haploid cells with only one copy of each chromosome in each cell.

Simply put, if gametes are not haploid, species with the same chromosomal number will not be preserved.

 Meiosis, a kind of cell division, is used to create these reproductive cells. A diploid parent cell, which has two copies of each chromosome, goes through one round of DNA replication followed by two cycles of nuclear division to produce four haploid cells during meiosis. These cells can become sperm or ova. Females' ova mature in their ovaries, whereas males' sperm develop in their testes.

Gametes are the reproductive cells of an organism. They're also known as sex cells. Sperm refers to male gametes, whilst ova or egg cells refers to female gametes. Gametes are haploid cells, meaning they have only one copy of each chromosome. These reproductive cells are created through meiosis, a type of cell division.

During meiosis, a diploid parent cell with two copies of each chromosome undergoes one round of DNA replication followed by two cycles of nuclear division, yielding four haploid cells. These cells have the potential to develop into sperm or ova. Male sperm develops in the testes, while female ova form in the ovaries.

Note:-
A cell that has two copies of each chromosome is known as a diploid. The germ line cells, which go on to form gametes, or egg and sperm cells, are the only exception. Haploid cells contain a single set of chromosomes, whereas germ line cells are haploid.
