Difference Between Mitosis and Meiosis 

In the life cycle of all cells there is a process that is relevant for them to survive and perform their functions. This cell division represents 10% of the total cell cycle. In this process, the mother cell divides into two or more daughter cells. According to the category of the cell it is known as  mitosis and meiosis.

What is mitosis and meiosis?

To understand the  differences between mitosis and meiosis, it is necessary to understand the three main types of cell division processes that exist:

  • Mitosis
  • meiosis
  • Binary fission

We are going to explain the difference between mitosis and meiosis, and at the end we are going to clarify what binary fission of cells is.

Mitosis

Mitosis is known as the process by which a eukaryotic cell separates all the chromosomes in its nucleus, resulting in two identical sets known as “daughter cells.”

In other words, a parent cell divides into two daughter cells that are identical to it. This is achieved by dividing the nucleus of the original (mother) cell into two parts. Importantly, daughter cells contain the same number of chromosomes as their parent.

The reproduction process of mitosis is asexual (does not need another cell to reproduce). This process allows the organism to clone exact copies of its original cell. This method is efficient and fast, but you cannot have diversity since each daughter cell is identical to the mother cell.

meiosis

Meiosis, unlike mitosis, is a type of sexual reproduction. These types of processes are necessary for sexual reproduction in eukaryotic cells .

The cells that are the result of the process of meiosis are known as spores or gametes. Gametes are sperm in men and eggs in women.

Now, meiosis differs from mitosis in key ways. Let’s go with the first one, meiosis produces four daughter cells with half the chromosomes of the original cells.

Mitosis in both produce two identical cells with the same number of chromosomes equal to the original.

Second, with meiosis genetic diversity is obtained, this thanks to the mixture of chromosomes, on the contrary, mitosis does not. Furthermore, mitosis is a method of asexual reproduction, and meiosis is a sexual process.

mitosis and meiosis differences

    • Mitosis produces two cells, while meiosis produces four cells.
    • Meiosis is sexual and meiosis is asexual.
  • In mitosis the number of chromosomes is the same in both mother and daughter cells, while in meiosis the daughter cells have only half the chromosomes of the mother cell.
  • Mitosis occurs in all organisms that contain eukaryotic cells. Meiosis only occurs in organisms where reproduction is sexual, that is, both parents are needed (male and female or male and female)

Binary fission

Process that takes place in prokaryotic cells , that is, it occurs in all unicellular organisms that lack a cell nucleus.
