Detailed explanation-1: -Somatic cells have the double number of chromosomes in gamete cells therefore the wing cells have 224 chromosomes.

Detailed explanation-2: -A sperm cell of a moth has 112 chromosomes.

Detailed explanation-3: -This division is an important event since after fertilisation haploid chromosomes from each gamete (male and female) fuse to retain the diploid state in the zygote. Diploid means two sets of chromosome and haploid is one set. Since here the diploid set is 16 thus one set will be half it, i.e, 8.

Detailed explanation-4: -Sperm is a male reproductive cell. The sperm is a haploid cell means it contains half the number of chromosome of the parent cell. A human contains 46 chromosomes in it. Thus, mature sperm contains 23 chromosomes.

Detailed explanation-5: -Cells of nematodes (worms), other than gametes, have 4 chromosomes. The number of total chromosomes in the non-gamete cells of a particular species is called the diploid number for that species. The diploid number of humans is 46, and the diploid number of nematodes is 4.
