23 pairs of chromosomes is called the diploid number.

Haploid is the term used to describe gametes (which contain half the normal number of chromosomes).
Human cells contain forty-six chromosomes each. An exception to this is gametes (oocytes and sperm), which contain twenty-three chromosomes each.
I will assume that you mean human cells. Somatic cells are diploid (2n), containing two sets of chromosomes, one of paternal, one of maternal origin. Gametes, on the other hand, are haploid (n), with a single set of chromosomes, ie. half as many as the somatic cell. Now, the haploid chromosome number (n) is characteristic of the species, and in humans this number happens to be 23. Therefore a human gamete has 23 chromosomes, and a human somatic cell 23 pairs, or 46 chromosomes.
A single complete set of chromosomes is called a haploid set of chromosomes. It is generally represented by the letter N. In humans for example, there are a total of 46 chromosomes per somatic cell. Since there are two copies of each chromosome. the 2N number for human is 46 and N = 23.
The haploid number (n) is the number of chromosomes in a gamete of an individual. This is distinct from the monoploid number (x), which is the number of unique chromosomes in a single complete set. Gametes (sperm, and ova) are haploid cells. The haploid gametes produced by (most) diploid organisms are monoploid, and these can combine to form a diploid zygote. For example, most animals are diploid and produce monoploid gametes.
The original question was not asking about "each new cell," but rather they were asking about the parent cell which is the start of meiosis. The answer is, each parent cell, NOT gamete cell, contains 46 chromosomes or is diploid, (2n). After the two divisions that occur in meiosis, the end result will be four haploid (n) cells or rather, four cells with 23 chromosomes each.
In human gametes, chromosomes are not paired. Instead, each gamete has one set of 23 chromosomes, and is said to be haploid.

When two gametes fuse during sexual reproduction, the single cell that forms is called a zygote. The gametes each have one set of chromosomes and are said to be haploid. When they fuse, they form the first diploid cell of the offspring, the zygote, which has two sets of chromosomes.
Gametes Have 23 Single Chromosomes, this means at fertilisation the pairs join together to make 23 pairs of Chromosomes. This is because Gametes are unspecialised cells so don't need all the Chromosomes that specialised cells have.
Meiosis in simple terms is the process by which gametes (sperm and egg) fuse together to produce a fertilised egg. Haploid is a word that refers to how many chromosomes a certain cell has. In this case the gametes have a haploid number of chromosomes, which is half the number a normal cell has. A normal cell has a diploid number of chromosomes. So in meiosis the two gametes come together with their hapoid number of chromosomes each to create an egg that has a diploid (standard) number of chromosomes.
Sex cells (better known as gametes) being product of meiosis have single set (haploid number) of chromosomes whereas body cells have diploid number. Thus, 22 pairs of autosomes and one pair of sex chromosomes (XY), thus 46 chromosomes are present in our body cells. The gametes (sex cells) contain only 23 chromosomes in each.
