Diploid cells
ploidy is the classification based on the number of homologous chromosomes present. if there is only one pair of homologous chromosomes then the nucleus is said to be haploid if there are two pairs then it is known as diploid if three it is triploid if many it is noted as polyploidy --------------------------- an oocyte or a spermatocyte are haploid cells in a species that normally have diploid cells.
The haploid number is the number of chromosomes within the nucleus of a cell that constitutes one complete chromosomal set. This number is commonly abbreviated as n, where n stands for the number of chromosomes. The haploid number will be different for different organisms. In humans, the haploid number is expressed as n=23.Haploid human cells have 1 set of 23 chromosomes:Autosomal chromosomes (non-sex chromosomes): 22 sets.Sex chromosomes: 1 set.Diploid human cells have 2 sets of 23 chromosomes for a total of 46 chromosomes:Autosomal chromosomes: 22 sets of 2.Sex chromosomes: 1 set of 2.
Diploid means to contain two sets of chromosomes. This is what the somatic (non-sex) cells of most organisms are. Haploid means to contain half the number of chromosomes of a diploid cell. This is what gametes (sex cells - sperm/egg) are.
The "haploid number" is the number of chromosomes in a given organism's reproductive cell (i.e., either sperm or egg or similar, depending on the species) or it's the number of pairs of chromosomes in an organism. They are easier to count just before mitosis or during the interphase of meiosis. So put a cell under a microscope, make sure it is in the right phase of reproduction and count the little "X's".
Human body cells that are 2n are called "diploid"

Have to say Nay. Two chromosomes are 'homologous' , to my understanding, only if each is IDENTICAL with the other - this means a pair. Gametes are haploid, meaning that only one copy of each (normally diploid or paired) chromosome (s) is (are) present.

Haploid cells are denoted n, and diploid cells are denoted 2n."n" refers to the set of chromosomes - therefore haploid cells have one set of chromosomes and diploid cells have two sets (pairs of chromosomes). Haploid cells have half the number of chromosomes as diploid cells.
24 since a haploid is half of the diploid containing 48 chromosomes
The haploid number is half the diploid number, making it six

human diploid numbers are 46 chromosomes (the total amount of chromosomes) and the haploid number is 23 (half the number of chromosomes) in meiosis the desired number is the haploid number for gametes (sex cells) and it becomes the diploid number after fertilization and for mitosis its the diploid number because it wants to maintain its chromosomes since its not sexual reproduction

it multiplies itself
Usually they dont as homologous chromosomes form bivalents with other homologous chromosomes and crossing over occurs between the 2. But if a chiasmata does form between the t homologous chromosomes they can change information.
