How Do Mitosis and Meiosis Differ in Cellular Division?

Mitosis and meiosis are two ways that cells divide, and they each have different jobs in living things.

What is it for? Mitosis helps with asexual reproduction, growth, and healing.
Steps involved: It has four main stages: Prophase, Metaphase, Anaphase, and Telophase.
Chromosome Count: The number of chromosomes stays the same (2n).
What it creates: Mitosis makes two cells that are just like the original one.
When does DNA Copy? DNA copies itself once before the cell divides.
How many times does it divide? There is one division (2n → 2n).
Where does it happen? It occurs in regular body cells, like skin and muscle cells.

What is it for? Meiosis is important for sexual reproduction and makes sperm and egg cells.
Steps involved: Meiosis has two parts: Meiosis I (where chromosomes mix) and Meiosis II (which is a lot like mitosis).
Chromosome Count: The number of chromosomes is cut in half (2n → n).
What it creates: Meiosis produces four cells that are different from each other.
When does DNA Copy? DNA copies itself once before Meiosis I.
How many times does it divide? There are two divisions (2n → n).
Where does it happen? This happens in sperm and egg cells.

Chromosome Numbers: In humans, body cells have 46 chromosomes (2n = 46), while sperm and egg cells have 23 chromosomes (n = 23).
How long do they take? Mitosis usually takes about 1 hour. Meiosis can take several hours or even days, depending on the organism.
Variation: Meiosis creates a mix of genes by mixing chromosomes, leading to many different combinations in human sperm and egg cells.

Knowing the differences between mitosis and meiosis is important for learning about genetics and cells.
