Ploidy refers to the number of sets of chromosomes in an organism. The ploidy of animal cells that are capable of meiosis is diploid.

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.
Are cells that exit meiosis immediately capable of fertilization?
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.
How does the daughter cells produced from meiosis differ from those produced by mitosis?
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)
Which of the following would be produced by meiosis red blood cell cells of the stem in plants sperm cell or epithelial cell?
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.
During cytokinesis what is a major difference between cell division in plant and animal cells?
The major in cell division (cytokinesis) in plant and animal cells is in plant cells, meiosis is only undergone from a spore to a sporophyte (from 2n to n) whereas in the animal cells, meiosis splits the sex cells into 4 new cells.
The ploidy of the end products of meiosis is?
The end process of meiosis is 4 haploid cells, or four n cells.

What are the only cells of the seminiferous tubules capable of BOTH mitosis and meiosis?
I believe the primary spermatocytes are the only seminiferous cells that are capable of that.
What occurs in plants and animal mitosis or meiosis?
Mitosis. Meiosis is only concerned in sex cells.

What is the ploidy of cells?
Human somatic cells are diploid, 2n. Human sex cells are haploid, n. Thus, the ploidy of human cells is 2, while n=23.
What is the ploidy of the cells of the tetrad of the pollen plant?
the cells are haploid

Why don't animal cell need chloroplasts?
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.
What are haploid cells also known as?
Ploidy
