Question:What are 4 major differences between Mitosis and Meiosis?
Answers:1.Mitosis is involved in growth and repair. Meiosis is involved in gamete production.
2.Mitosis produces two cells from one parent cell. Meiosis produces four cells from one parent cell.
3.Mitosis produce diploid cells. Meiosis produces haploid cells.
4.Mitosis has one round of division. Meiosis has two rounds of division.
5.Mitosis produces two identical cells. Meiosis produces genetically different cells.
Question:List 4 ways in which meiosis differs from mitosis
Answers:1. Meiosis creates 4 cells, while mitosis creates 2
2. The cells created in meiosis are genetically unidentical; in meiosis, these cells are identical
3. Meiosis has two divisions (Meiosis I and II) that occur to create cells while mitosis only has one division
4. Meiosis creates gametes (sex cells) whereas mitosis creates somatic cells (normal body cells)
Question:I have several question with meiosis and mitosis, someone with a kind heart please help... :) I've been having trouble understanding this topic and we will be dicussing it next week and I just want to know it before we actually discussed this in school...some of it i understand but I want to make sure that I really "understand" it..
1. What is the significance of mitosis?
2. What is the significance of meiosis?
3. What does mitosis mean for a unicellular organism and multicellular organism? ( I mean what do they do for each organism?)
4.What is the difference between mitosis and meiosis? (could you please be specific)
5. what is the different between animal and plant mitosis? actually this is not a homework. yes, we have been asked to read about the topic much early before we discuss it but thats just it.
I just wanna understand it so I could participate during our class discussion because the teacher have been humiliating me in class whenever i cant answer his question and its terrible. So if I thought if I study this then the next time he would ask me I can answer his question, besides our book is way too confusing and english is not my first language so i have trouble understanding it...I just need someone to help me understand it...thats all :) you dont have to answer it specifically just the basic stuff thats all........... thanks for those who have been answering my questions...im getting a clear view of it now and im getting excited for our class tom. cant wait to let see my teacher that i have been studying harder
Answers:1.) Mitosis is required for growth and for repairing. Once a sperm and an egg meets or fuses together to form a zygote, the cell undergoes mitosis to form an individual. Also if you kill your own cell, the body compensates this by producing another one of exactly the same type by mitosis.
2.) Meiosis is required for producing sex cells or also known as gametes. Overall meiosis involves 2 cell divisons resulting in the formation of 4 new cells known as the daughter cells. Meiosis is important because it creates variation..well why is variation important?... well say you have a population of organism of the same type with same characteristics, once a disease is encountered and kills one of them, the whole lot will die out and the species will eradicate completely.. so having variation prevents this, because there will be one organism that will have the characteristics to survive this disease..
3.) Unicellular organisms are made from one cell only, so if this cell undergoes mitosis an identical cell will be produced. For unicellular organism mitosis might be helpful for populating the habitat and for multicellular organism it is important for repair.
4.) Mitosis only has one cell division and meiosis has two cell divisions. Mitosis produces two daughter cells as the by-product while meiosis produces 4. Mitosis does not create variation but meiosis does. Also the two new daughter cells created by mitosis are diploid meaning full number of chromosomes are found while for meiosis the 4 cells created are haploid meaning half the number of chromosomes are found.
5.) Mitosis involves the use of centrioles. Plant cells dont have centrioles but animal cells do. Overall the same result is encountered.
hope it helps :)
Question:Please compare meiosis and mitosis using the following components;
1. Number of parent cells
2. Basis for which type of reproduction
3. Number of daughter cells
4. Haploid or diploid cells?
5. Number of times cells divide in two
Answers:1. There is only one parent cell involved in both meiosis and mitosis.
2. Mitosis occurs in both, sexually as well as asexually reproducing organisms. However, meiosis occurs only in sexually reproducing organisms.
3. Mitosis results in two daughter cells whereas meiosis results in four daughter cells.
4. Meiosis produces haploid daughter cells whereas mitosis produces diploid cells.
5. In meiosis, a cell divides two times whereas in mitosis, a cell divides only one time.
Meiosis :Lyrics: Starts in the S phase, DNA replication Sister chromatids appear They condense further than they had before Attach at the centromere Homologous pairs, always been there, Never met up before They exchange pieces, then crossing over ceases Line up in no particular order Nobody said it was easy to learn It's not a shame for them to part Nobody said it was easy to learn It's so important that chromosomes part Variation at the start At the metaphase plate chromosomes in tetrad state Attach to the microtubules After anaphase I, the centrosomes job is half done Chromosomes move to opposite poles In telophase I, meiosis is half done Haploid cells are formed by the split But there's still stuff to do; after all, there are two Sister chromatids -- Meiosis II begins Nobody said it was easy to learn It's not a shame for them to part Nobody said it was easy to learn It's so important that chromosomes part Variation at the start Repeat the process, form the spindle apparatus Chromosomes move to the plate Crossing over changed them -- after all, it exchanged them So chromatids are in a non-identical state The next steps are the same, and look what one cell became Four different haploid daughter cells Create variation for the next generation It made you unique as well.
