Gametes (sex celles) such as egg and sperm only contain one set of chromosomes this is is called a hapliod nucleus. when the 2 meet this forms a full pair of chromosomes and makes a dapliod nucleus.
Prokaryotic cells
i.e. Chromosomes are contained within the nucleus of a cell. Therefore, for a cell not to have chromosomes, it must not have a nucleus, hence prokarytic cell.
Except for red blood cells, which despite not having a nucleus are regarded as eukaryotic.
Haploid is cells without pairs, Diploid cells however have pairs of chromosomes
Gametes also known as sex cells, which are the sperm and egg cells.
The sex cells or gametes are haploid cells (one set of chromosomes) with half the number of chromosomes as diploid cells (two sets of chromosomes).

Haploid
It will depend on the animal - the number of chromosomes varies from species to species. Somatic cells are non-sex cells. This means that in sexually reproducing animals, somatic cells usually have 2 pairs of chromosomes (they are called diploid cells). Human somatic cells have 46 (23 pairs of) chromosomes. Cat somatic cells have 38 (19 pairs of) chromosomes. Dogs have 78 (39 pairs of) chromosomes.
Human sex cells which only have a haploid number of chromosomes. 23 total chromosomes. Red blood cells have no chromosomes also.
Human cells have 23 homologous pairs. They also must go through meiosis before that. Females have 2 X chromosomes, while Males have an X and a Y chromosome. That's why the males cells decide the gender of the child.
There are 23 pairs * 2n = 46 chromosome pairs.
there are 23 pairs of matching chromosomes 46 chromosomes altogether.
Hapliod cells have no pairs of chromosomes
Haploid cells have no pairs of chromosomes.

Each human cell has 23 pairs of chromosomes or 46 chromosomes.

Dogs have 37 pairs of chromosomes. As with pairs of shoes, the number of pairs is multiplied by 2 to get the total number of chromosomes in a dog's body cells. Therefore, the total number of chromosomes in a dog's body cells is 76. Sex cells, (sperm or eggs) have half of the pair, so would have 34 chromosomes. ________ The above is incorrect, dogs have 78 chromosomes meaning they have 39 pairs.
