What is the process for producing sperm?
The process of producing sperm cells is called spermatogenesis. Sperm production begins before puberty through the increase in the number of precursor cells called spermatogonia. They in turn double in number through mitotic cell division and become primary and secondary spermatocytes. Then through two stages of cellular division called meiosis, the primary spermatocytes become 4 spermatids, which then further develop into spermatozoa, or sperm.With regard to the cellular divisions involved, mitosis maintains the same number of chromosomes (46 in humans) in the nucleus of the resulting twin daughter cells after division, whereas in meiosis, the four resulting daughter cells have only 23 chromosomes each.
What is the ploidy of cells of aleurone layer in cereal grains?
The aleurone layer is the outermost layer of the endosperm. Therefore it is also triploid and same as the ploidy of endosperm.
What had happen to the ploidy at the end of the process of mitosis?
At the end of mitosis two daughter cells are produced identical to the parent cell. If the parent cell is haploid the daughter cell will be haploid. If the parent cell is diploid the daughter cell is also diploid.
How are primary and and secondary are same?
there not
Does the ploidy of a cell change when it divides by mitosis Why or why not?
It does not change. Mitosis results in two identical cells with exactly the same number of chromoses. Mitosis occurs in somatic cells for the purpose of growth of tissues, unlike meiosis which occurs in sex cells prior to fertilisation. while mitosis starts and ends as a 2n cell the part about it not changing is wrong. mitosis starts off as 2n then each chromatid replicates creating a 4n cell in prophase until it reaches telophase it goes back to 2n as the chromatids separate at the poles, and the daughter cells are formed.
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 are primary and secondary succession same?

What are related colors?
Related colour's are when the secondary colour and another secondary colour have the same primary colour.
Are primary and secondary consumer's the same thing?
No, the primary consumer are herbivores whereas the secondary consumer is carnivores.
What color related?
Related colour's are when the secondary colour and another secondary colour have the same primary colour.
