Mitosis vs. Meiosis answer chart

Answer:

why do cells divide is mitosis

mitosis is understood to involve five phases

how many daughter cells produced in mitosis two

how many daughter cells produced in meiosis four daughter cells

A condition in which every cell in the body has an extra set of chromosomes is not compatible with life. In some cases, a change in the number of chromosomes occurs only in certain cells. When an individual's cells differ in their chromosomal makeup, it is known as chromosomal mosaicism .

HOPE  THIS helps

Explanation:

Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.

[tex]\Large{\textbf{Meiosis:}[/tex]

       The stages of Meiosis 1 are,

                                            (a) Prophase (which is sub-divided into 5 more  stages which are Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis)

                                             (b) Metaphase,

                                             (c) Anaphase,  

                                             (d) Telophase.

        The Stages of Meiosis 2 are, Prophase, Metaphase, Telophase and Anaphase which are same as mitosis.

     3. In meiosis, Cell divides twice.

     4. In meiosis, 4 daughter cells are produced.

     5. Yes, the chromosomal number in mitosis is reduced to half than normal i.e. 23

     6. In meiosis, the final result is 4 haploid cells. If meiosis occurs in male then these haploid cells will be called sperms, if it occurs in female then they are called Ova(egg).

Just to give you some insight knowledge of Meiosis Im adding some extra points

[tex]\Huge\textbf{Meiosis:}[/tex]

Meiosis is a special type of cell division, which occurs only in the germ cells during the process of development and maturation to form gametes. It consists of two successive cell divisions,

Meiosis 1 : First meiotic division, that reduces the NUMBER of chromosomes i.e. the parent cell is diploid(46 Chromosomes) and the daughter cells are haploid(23 Chromosome). It also causes genetic variation in the haploid by cross linkage.

Meiosis 2 : Second meiotic division (Meiosis II) starts with two haploid parent cells and ends with four haploid daughter cells. Meiosis 2 like Meiosis 1, does not reduce the NUMBER OF CHROMOSOME that means the forming 4 daughter cells are haploid and their number of chromosome remains the same as the parent. BUT Haploid cells that go into the meiosis 2 have MORE AMOUNT OF CHROMOSOME THAN USUAL, thus MEIOSIS 2 REDUCES the amount of chromosome rather than the number of chromosome.

The DNA of the primitive germs cells is replicated prior to the meiosis 1 only and there is no replication of DNA before Meiosis 2. The four final cells reulting from the two meiotic divisions are not only haploid(i.e. containing 23 chromosome) but they are also containing 1n amount of DNA so that when the gametes fuse together forming a zygote, both the amount and number of chromosome and DNA remains SAME.

[tex]\Large\text{Why is Meiosis Important?}[/tex]

Meiosis is essential for the sexual reproduction of eukaryotic organisms because it enables genetic diversity through recombination, and the repair of genetic defects.

It contributes in genetic reassorment which ensures the genetic diversity in the offsprings. The genetic reassortment takes place by following two mechanisms:
