This is an impossible question to answer the way it is phrased. One needs to know what plant species is being discussed before the question can be answered. Each species will have a unique number of chromosomes and its pollen will have half as many as the parent species.
Cells which contain half the number of chromosomes (compared to a normal cell) are known as haploid cells. An example of haploid cells is gametes or sex cells.
Gametes are cells, in humans they contain 23 chromosomes. Body Cells (Properly Called: Somatic Cells) in humans contain 46 chromosomes (2 sets of 23). Some differences or problems can cause this number to change in specific humans, gametes, and somatic cells. Muscle cells may have hundreds of chromosomes, red blood cells have none.
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.
All human gametes (sex cells), which means egg cells and sperm cells, have 23 chromosomes. When the sperm fertilises the egg, the 23 chromosomes from the egg cell and the 23 chromosomes from the sperm cell join to make cells with 46 chromosomes. In summary, all cells in the human body have 46 chromosomes, except sperm cells and egg cells, which have 23.
Somatic cells are cells in the body other than egg, sperm, or pollen. They have a full set of DNA. For humans there are 23 pairs of chromosomes for a total of 46 chromosomes.
23 chromosomes for every 1 sex cell??

No, a gamete has half the number of chromosomes as compared to the organisms body cells.
Sex cells have 23 chromosomes compared to the body cells' 46 chromosomes. This is because a child is created from half the genome of its father and half the genome of its mother. In other words, 23 chromosomes in the mother's egg and 23 chromosomes in the father's sperm, when combined generate a child with 46 chromosomes in its body cells. However, sometimes mutations occur where more of fewer chromosomes are passed down, this will either result in no embryotic development or the embryo having some kind of syndrome.

A haploid reproductive cell that unites with another haploid reproductive cell to form a zygote.The term is used for egg and sperm cells also pollen. They have half the number of chromosomes compared to other cells in the body (23 individual chromosomes for human.) The name derives from the Greek gamete, meaning wife, and gametes, husband, both from gamein, to marry.
The ovule is enclosed within the ovary, and contains the female gamete which has the haploid. (number of chromosomes)
Reproductive system. Meiosis is the formation of gametes which unlike regular cells have 23 unpaired chromosomes compared to regular cells which have 23 paired chromosomes or 46 total chromosomes, in humans that is.
In the sex cells you only have half of the number of chromosomes- 23 instead of 46 which is what you have in your other body cells This is because when the sperm fertilizes the egg, the two nuclei fuse together and the chromosomes combine so you then have the right number for normal body cells to develop in the baby.
sex cells(gametes) are haploid in nature as compared to body cells(somatic cells) thus the number of chromosomes in a sex cell of a grasshopper is half the number of chromosomes in a body cell
Cells which contain half the number of chromosomes (compared to a normal cell) are known as haploid cells. An example of haploid cells is gametes or sex cells.
