All cells follow a process of division and this process is very relevant in their life cycle. Cell division represents 10% of the cell cycle. It is a process by which a stem cell divides into two or more daughter cells . what is the main difference between Mitosis and Meiosis
There are three main types of cell division processes : binary fission , mitosis, and meiosis .
Next we are going to explain what the difference is between mitosis and meiosis, since they probably left it for you as homework at school.
Note: binary fission takes place in prokaryotic cells, that is, in unicellular organisms that lack a cell nucleus. Only eukaryotic cells, which are those that have multicellular organisms; whose cells contain complex structures within their membranes, undergo mitosis or meiosis . (All these processes are methods of reproduction and replication the DNA ).
MITOSIS what is the main difference between Mitosis and Meiosis
Mitosis is the process by which a eukaryotic cell separates the chromosomes in its nucleus , resulting in two identical sets . These are called ” daughter cells.”
Essentially , one cell ( the mother cell ) divides into two cells ( the daughter cells ), which are identical to it . This is done by dividing the nucleus of the original cell into two parts . The daughter cells contain the same number of chromosomes as the cell mother.
Mitosis is a form of asexual reproduction . This allows an organism to clone exact copies of the original cell . This method of reproduction is fast and efficient , however, it does not allow for diversity; since all products are identical to the cell from which they originate.
Meiosis, on the other hand, is a type of sexual reproduction . It is a special type of cell division necessary for sexual reproduction in eukaryotes.
The cells resulting from meiosis are gametes or spores . Gametes are sperm and ovules in most organisms (they are sex cells) , common in both animals and plants.
In the process of meiosis , a cell that contains two copies of each chromosome , one from the mother and one from the father ( the zygote – which is a female egg fertilized by male sperm ), produces four cells that contain a copy of each chromosome. The result is a unique mix of maternal and paternal DNA . This allows the offspring to be genetically different from either parent . Meiosis introduces genetic diversity within the population.
Meiosis differs from mitosis in important ways . First, because it produces four daughter cells with half the chromosomes of the original cells ; while mitosis produces two daughter cells with a chromosome number identical to the original cell . Second , meiosis leaves room for genetic diversity ; since it allows the mixing of chromosomes , while in mitosis this does not occur . Finally, mitosis is a method of asexual reproduction, while meiosis is sexual.
Key differences between meiosis and mitosis
- Mitosis is asexual, while meiosis is sexual.
- In mitosis, the stem cell divides in two; while in meiosis it is divided into four.
- In meiosis, daughter cells have only half the chromosomes of the original cells; while in mitosis the number of chromosomes is the same in both stem cells and daughters.
- Mitosis occurs in all organisms with eukaryotic cells, while meiosis only occurs in organisms whose reproduction is sexual (that is, they need both parents).
