Mitosis is a process of cell division that results in two genetically identical daughter cells from a single parent cell. It consists of several stages:

1. Prophase: Chromatin condenses into chromosomes, and the nuclear envelope breaks down.

2. Metaphase: Chromosomes align at the cell's equatorial plane.

3. Anaphase: Sister chromatids are pulled apart to opposite poles.

4. Telophase: Nuclear envelopes reform around each set of chromosomes.

5. Cytokinesis: The cytoplasm divides, resulting in two separate cells.

Mitosis is essential for growth, repair, and asexual reproduction in organisms.
