Ploidy refers to the number of sets of chromosomes in an organism. The ploidy of animal cells that are capable of meiosis is diploid.
During meiosis I, the DNA content is halved as homologous chromosomes separate, leading to haploid daughter cells. In meiosis II, sister chromatids separate without DNA replication, resulting in four haploid daughter cells with the same DNA content as the parent cell before starting meiosis.
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.
At the end of meiosis, haploid cells are produced. These cells need to further develop into mature gametes capable of fertilization, a process called gametogenesis.
Meiosis would produce sperm cells and epithelial cells in plants. Red blood cells do not undergo meiosis, as they lack a nucleus and are not capable of dividing.
What I remember from school was that meiosis split into 4 cells and that mitosis split into two cells and I think that meiosis happened when cells were trying to repair something and mitosis was for reproduction. (Remember miTosis=Two)

The phase that results in a change of ploidy from diploid 2n to haploid n is meiosis. Meiosis is a type of cell division that occurs in sexually reproducing organisms, resulting in four daughter cells with half the number of chromosomes as the parent cell.
I believe the primary spermatocytes are the only seminiferous cells that are capable of that.
The end products of meiosis are haploid, meaning they contain half the number of chromosomes as the original cell. This is achieved through two rounds of cell division, resulting in four daughter cells that are genetically distinct from each other.
At the end of meiosis, haploid cells are produced. These cells need to further develop into mature gametes capable of fertilization, a process called gametogenesis.
Mitosis. Meiosis is only concerned in sex cells.
Human somatic cells are diploid, 2n. Human sex cells are haploid, n. Thus, the ploidy of human cells is 2, while n=23.
Ploidy reduction is a process in which the number of sets of chromosomes in a cell is reduced. This can happen during meiosis, the process of cell division that produces gametes (sperm and egg cells) with half the normal number of chromosomes. Ploidy reduction is important for sexual reproduction to maintain the correct chromosome number in the offspring.
Animal cells are not capable of photosynthesis hence these cells lack chloroplasts. We can also put it this way, that since animal cells lack chloroplasts, these are not capable of photosynthesis.
