This is my first time using Jishka. Well, registering and using the site. I have checked the site when researching class topics we are learning. I don’t think I really have a question but I am looking for clarity of something for class. I just want to make sure that I have the correct understanding of meiosis and mitosis. In humans, mitosis is important because it produces the identical chromosomes that are in our DNA. Meiosis is important because it multiplies the number of cells with cell division, and reduces the number of chromosomes in each daughter cell by half the number before meiosis. If I do not have this correct, can you please tell me what I am not grasping about the importance of mitosis and meiosis in humans.
I was not asking for my homework to be done. I was simply asking if I had the correct understanding of mitosis and meiosis. I didn't even put the question into my post from my homework. I thought this was a website to help people with their homework, etc. I have read other posts where someone would ask if they were correct and given an answer, I think that is a little unfair
I don't mean to sound ungrateful because this website has really helped me a lot..The first time I posted a question, which was not even an assignment question but to make sure I had the correct understanding of the material I was learning I was told we do not do the homework for you but will help. I have see responses to questions on this site which is doing homework for students. I know because they are questions I have had in previous courses. You would think when someone comes on here and says they would like clarification that someone would offer to help them, instead of saying we do not do the homework for you.
You have a good start in understanding the basics of mitosis and meiosis, but let's clarify a few things.
Mitosis is the process of cell division that occurs in somatic cells (non-reproductive cells) in our bodies. Its main purpose is to produce two identical daughter cells, each with the same number of chromosomes as the parent cell. This process plays a crucial role in growth, tissue repair, and asexual reproduction in organisms.
On the other hand, meiosis is a specialized type of cell division that occurs only in cells involved in sexual reproduction, such as the cells that form eggs and sperm. Its main importance lies in the reduction of the chromosome number by half in the resulting daughter cells. By reducing the number of chromosomes, meiosis ensures that when two gametes (sperm and egg) fuse during fertilization, the resulting zygote will have the correct number of chromosomes. In humans, meiosis produces cells with 23 chromosomes, which allows for the restoration of the diploid chromosome number (46) when fertilization occurs.
So, to summarize:
- Mitosis generates identical cells and is important for growth, repair, and asexual reproduction.
- Meiosis reduces the number of chromosomes and is crucial for sexual reproduction to ensure the correct chromosome number in offspring.
If you need further clarification or have any specific questions about mitosis and meiosis, feel free to ask!
