Differences between Mitosis and Meiosis

Differences between Mitosis and Meiosis

Hi friends, Today let us figure out the differences between Mitosis and Meiosis. Many of us get confused during the exam of Biology or when our teacher/sir asks us. So let us learn what are the differences between mitosis and meiosis in detail also without confusion.

Cell-cycle is one of the most breathtaking processes that help the cell to not only grow but also divide we know that a cell cycle has two major phases one helps in the preparation of the cell for the division.

Now, can you name the preparatory phase of the cell cycle? that’s the right answer. It’s called the interphase and moving to the other phase it carries out the sijin of the cell.

Now answer me what does that phase is called? correct it’s the M phase where M stands for either mitosis or meiosis.

How does the cell decide whether to undergo mitosis or meiosis? That depends on various factors and the type of cell undergoing division. The first difference between the two processes, Mitosis occurs in somatic or body cells while Meiosis occurs exclusively in the reproductive cells.

That means mitosis occurring irrespective of whether the individual is a male or a female gives rise to Somatic cells which are exact copies of the parent cells. On the other hand, meiosis occurs in males and females giving rise to haploid sperm and egg cells respectively.

The process of meiosis however has different names in both sexes yes due to the different cells produced as an end result in meiosis is also referred to as our Genesis.

That is the process of ovum production in females and spermatogenesis that is the sperm production process in males another major difference is that mitosis is used as a mode of asexual reproduction in lower organisms.

While meiosis helps in forming gametes for sexual reproduction. Now let’s move ahead with the next difference. Mitosis has only one cell division while meiosis involves two successive cell divisions that simply means mitosis is a single step division.

While meiosis is a two-step division and, results in meiosis having two phases namely meiosis one and meiosis two. Mitosis produces two daughter cells while Meiosis produces four daughter cells.

Moving to the next major difference. This difference is based on the chromosomal number of the daughter cells in mitosis the daughter cells are diploid with two sets of chromosomes just like the pair itself while during meiosis.

The daughter cells produced are haploid with only one set of chromosomes these daughter cells are called gametes have exactly half the number of chromosomes from the parent cells.

One more difference is that all the four daughter cells produced by meiosis are genetically different from each other while the two daughter cells that are produced by mitosis are genetically similar to each other.

Now let’s move on to the next difference but before that can you tell me, How many stages of division does the mitosis process have? correct it has four stages of division. And is it the same for meiosis as well the answer is definite?

No, since meiosis involves two rounds of division that is meiosis 1 and meiosis 2 the process has a total of eight stages of division. Moving on to the next difference, This point has been studied by us in the lower grades as well.

We have studied that. mitosis occurs in all organisms except viruses and which organisms can have meiosis, Meiosis occurs only in plants, animals, and fungi.

Now, let’s dive deeper and compare the stages of mitosis and meiosis to explore some more differences between them.

The first stage of meiosis one which is prophase one is very long consisting of five sub-stages. On the other hand, the prophase of mitosis is comparatively shorter than prophase one crossing over does not occur in prophase.

While definitely occurs in prophase one independent assortment is technically absent in the metaphase of mitosis while it occurs in metaphase. The separation of chromatids takes place during anaphase.

On the other hand, the separation of homologous chromosomes takes place during anaphase one and the separation of sister chromatids during anaphase two.

So these were the major differences between mitosis and meiosis. Have you ever wondered what important tasks do these two processes perform in our bodies?

Mitosis helps in the healing and repairing of the cells and tissues of our body. It’s also responsible for the growth and development of the body.

Meiosis however helps exclusively introduce gametes this ensures genetic diversity.

So friends, Hope you are clear now and if you still have a doubt in this comment down in comments section.
