Mitosis
* What it does: Mitosis is responsible for growth and repair in multicellular organisms. It creates two identical daughter cells from one parent cell, each with the same number of chromosomes.
* Who uses it: All multicellular organisms, including plants, animals, and fungi, use mitosis for growth and repair. It's also the process by which single-celled organisms reproduce asexually.
Meiosis
* What it does: Meiosis is responsible for sexual reproduction. It starts with one parent cell and produces four daughter cells, each with half the number of chromosomes as the parent cell. This is crucial for creating gametes (sperm and egg cells) which combine to form a new organism with a unique genetic makeup.
* Who uses it: All organisms that reproduce sexually use meiosis to create gametes. This includes most plants, animals, fungi, and some protists.
In summary:
* Mitosis: Growth, repair, asexual reproduction
* Meiosis: Sexual reproduction (creating gametes)
