- Mitosis is a form of cell division where the cell splits into two, each identical to the original cell.
- Meiosis is a type of cell division that results in four cells, each having half the number of chromosomes of the original cell.
- The similarities between mitosis and meiosis are as follows: Mitosis and meiosis take place in the cell nuclei. Both involve cell division. Both th...
Learn the meaning, function and occurrence of mitosis and meiosis, two types of cell division in biology. Compare and contrast their features, such as number of divisions, chromosomes, crossing over and type of reproduction.
Sep 12, 2023 · Learn the differences between mitosis and meiosis, the two types of cell division in eukaryotes. Mitosis produces identical daughter cells for growth and repair, while meiosis produces non-identical daughter cells for sexual reproduction and genetic diversity.

Mitosis and meiosis are both types of cell division. Though there are similarities between mitosis and meiosis, there are some key differences between these two processes. Mitosis is how new body cells are produced, whereas meiosis is used to produce gametes (i.e. sperm and egg cells).
Mitosis is how the cells of your body reproduce. During mitosis, a diploid parent cell (i.e. a cell with two sets of chromosomes) makes a complete copy of its DNA before splitting in two. This process produces two genetically identical daughter cells and takes place across five phases. The phases of mitosis are prophase, prometaphase, metaphase, an...
Almost all of your body’s cells divide by mitosis. Meiosis is used to produce only one type of cell, and those are the gametes. During meiosis, a diploid cell divides to produce four, non-identical haploid daughter cells, each containing a single set of chromosomes. In humans, these are sperm and egg cells. Unlike mitosis, meiosis involves two roun...
Meiosis I
Like mitosis, meiosis I takes place across five stages. Before this first round of cell division begins, the cell’s DNA is replicated during the interphase of the cell cycle.
Meiosis II
Meiosis II is very similar to the process of mitosis, except it involves two haploid cells rather than one diploid cell.

Learn the similarities and differences between mitosis and meiosis, two processes of cell division. Mitosis creates identical body cells, while meiosis creates genetically diverse sex cells for sexual reproduction.
Mitosis and meiosis are two different types of cell division. Mitosis occurs in somatic cells and results in two identical daughter cells with a diploid (2n) number of chromosomes. This process is essential for growth and repair in the body. On the other hand, meiosis occurs in germ cells and produces four non-identical gametes with a haploid ...
