* Single-celled organisms don't reproduce sexually. They don't combine genetic material from two parents.
* Mitosis creates two identical daughter cells. This means the offspring are genetically identical clones of the parent cell.
* This is how they reproduce and increase their population. Think of it as a form of "cell division" that creates new individuals.
Examples:
* Bacteria use binary fission, which is essentially a simplified version of mitosis.
* Amoeba divide asexually through mitosis.
* Yeast also reproduce asexually via budding, which is a form of mitosis.
Benefits of Asexual Reproduction through Mitosis:
* Efficiency: It's fast and requires less energy than sexual reproduction.
* Favorable conditions: In stable environments with plentiful resources, producing genetically identical offspring can be advantageous.
Limitations:
* Lack of genetic diversity: All offspring are identical, making them susceptible to the same environmental threats.
* Evolutionary limitations: Asexual reproduction limits the rate of adaptation to changing environments.
