What best describes the sperm cells of an animal that are produced from primary sex cells?
They contain the monoploid number of chromosomes.

Is secondary spermatocyte haploid or diploid why?
secondary oocytes are haploid cells carrying 23 chromosomes. After fertilization by sperm a Zygote is formed with a diploid number 46.
Sperm are produced within the testes by the process of?
Spermatogenesis- takes place in the seminiferous tubule of the testesIt is the form of gametogenesis taking place in males and utilises the two forms of nuclear division to produce a haploid gamete.A cell from the germinal epithelium (2n) divides by mitosis to form the spermatagonia (2n), which then develops into the primary spermatocyte (2n). The primary spermatocyte divides by meiosis 1 to form the secondary spermatocyte (n), which divides by meiosis 2 to become the spermatid (n). This spermatid develops and matures in the epididymis to form the final spermatazoon (or just sperm)Germinal epithelium --> Spermatagonia --> Primary spermatocyte --> Secondary spermatocyte --> Spermatid --> Spermatazoon

Why do you get sperm?
I get sperm for my biological purpose. That is, to sexually reproduce. If you are a male; I would assume that's the same reason why you get sperm. If your female; then I'm worried deeply about you. If you're wondering where sperm comes from or how it's made... I can tell you that it's made from the human body. Specifically, by the DNA which provides information to create the sperm cells (like a manual). The making of sperm is called spermatogenesis. Sperm are basically complex cells which simply contain the males genetic code. Sperm cells come from spermatogonium. Spermatogonium contains 46 chromosomes. It duplicates it DNA and divides by meiosis. One cell becomes a Spermatogonium (which will undergo this process again) and another becomes a primary spermatocyte, each cell has 46 chromosomes. The spermatocyte divides by meiosis to produce two secondary spermatocytes, each containing 23 chromosomes. These divide again to provide spermatids, each with 23 chromosomes. Then the spermatids differentiate into sperm cells, all containing 23 chromosomes which will be paired up with 23 others upon fertilization (sex). Spermatogenesis takes place in the testicles.
How many functioning sperm are produced from one spermatocyte?
4
If the body cells of humans contain 46 chromosomes a single sperm cell should have?
A primary spermatocyte with 46 chromosomes will undergo meiosis and yield four spermatids with 23 chromosomes. A primary spermatocyte undergoes meiosis I two haploid secondary spermatocytes are produced.

Spermatogonia, spermatocyte, spermatid, spermatozoa
