To prevent the chromosome number from doubling every generation.
Sexual reproduction involves two cells (gametes) combining their chromosomes. The process is fertilization, and the product is a zygote.
If each gamete has a single set of chromosomes (as happens in humans, most other animals, and many plants) the zygote will have two sets of chromosomes. Whatever the zygote grows into, whether a person, pelican, or pineapple, every cell in the body will have two sets. If the gametes also have two sets each, the next zygote will have four, and so on, until you need a wheelbarrow to carry your chromosomes around!
So every life-cycle that includes a doubling of the chromosome number also includes a halving, and that process is called meiosis. Meiosis occurs at different times in different life-cycles. In humans meiosis happens when the gametes are being formed, but in plants it happens when spores are being formed.
Diploid gametes are not a product of meiosis. Meiosis is the process by which diploid cells undergo two rounds of division to produce haploid gametes. The haploid gametes then join during fertilization to form a diploid zygote.
Gametes produced in insects are haploid. This means they have half the number of chromosomes as diploid cells in the insect's body. When two haploid gametes (one from each parent) fuse during fertilization, they form a complete diploid zygote.

Gametes.
The function of a haploid cell is to participate in sexual reproduction, where it combines with another haploid cell to form a diploid cell containing genetic material from both parents. In humans, haploid cells are sperm cells in males and egg cells in females.
Gametes are haploid in terms of their genetic composition.
Gametes are haploid, meaning they have half the number of chromosomes as diploid cells.
The haploid condition is desirable in gametes because two haploid cells come together to make one full cell. If the gametes were not haploid then the organism would have too many chromosomes.
Gametes are haploid, meaning they contain half the number of chromosomes compared to other cells in the body. This haploid state allows for the fusion of two gametes during fertilization to form a diploid zygote with a complete set of chromosomes.
Diploid gametes are not a product of meiosis. Meiosis is the process by which diploid cells undergo two rounds of division to produce haploid gametes. The haploid gametes then join during fertilization to form a diploid zygote.
Haploid gametes have half the number of chromosomes as a diploid cell, so in humans, there are 23 chromosomes in a haploid gamete.

Human female haploid gametes are called eggs or ova.
