Write an essay that details the structure and function of a eukaryotic cell, how its cell membrane functions, and details of how that cell will carry out mitosis and meiosis.

OpenStudy (matt101):

The first two questions you got correct. For the question about oogenesis, the answer is actually ONE cell. I can explain why if you need. During spermatogenesis, FOUR cells develop by meiosis. Reduction of the number of chromosomes occurs during meiosis I, as you said. However, replicated chromosomes (that is, double stranded chromosomes), are separated during MEIOSIS II. As for the essay...I can't write it for you, but if you have any specific questions or things you don't understand I can try to help you out!

Thank you thank you for your answers. It it so informative.

I know you can't write me an essay. But can you please give me some idea on how to write it please?

OpenStudy (anonymous):

May I ask what school are you study?

OpenStudy (anonymous):

Have you done this kind of questions before?

OpenStudy (matt101):

Well for the structure/function of the eukaryotic cell, you can talk generally about it being a membrane-bound compartment that contains a bunch of organelles that carry out various cellular functions as well as a nucleus where DNA is stored. The main function of the cell membrane is to isolate what's inside the cell from the external environment, and therefore create an optimal environment INSIDE the cell for various processes to be carried out. All specific functions relate to this one (e.g. selective permeability to various molecules, establishing concentration and electrical gradients, etc). Mitosis and meiosis you can summarize easily, just make sure you emphasize the differences between the two processes as well as which cells they are most likely to occur in!
