1. Mitosis: This is the process of cell division that creates two identical daughter cells from a single parent cell. It's how our bodies grow and repair tissues. Here are the stages of mitosis:
* Prophase: The chromosomes condense and become visible. The nuclear envelope breaks down, and the spindle fibers start to form.
* Metaphase: The chromosomes line up at the center of the cell, with each chromosome attached to a spindle fiber at its centromere.
* Anaphase: The sister chromatids separate and move to opposite poles of the cell.
* Telophase: The chromosomes reach the poles of the cell, the nuclear envelope reforms around them, and the cytoplasm divides, forming two daughter cells.
2. Meiosis: This is the process of cell division that produces four daughter cells, each with half the number of chromosomes as the parent cell. This is how our bodies create gametes (sperm and egg cells) for sexual reproduction. Meiosis is more complex than mitosis and has several stages:
* Meiosis I:
* Prophase I: The chromosomes condense, homologous chromosomes pair up (synapsis), and crossing over occurs.
* Metaphase I: Homologous chromosome pairs line up at the center of the cell.
* Anaphase I: Homologous chromosomes separate and move to opposite poles of the cell.
* Telophase I: The chromosomes reach the poles, the nuclear envelope reforms, and the cytoplasm divides, forming two daughter cells.
* Meiosis II:
* Prophase II: The chromosomes condense.
* Metaphase II: The chromosomes line up at the center of the cell.
* Anaphase II: Sister chromatids separate and move to opposite poles of the cell.
* Telophase II: The chromosomes reach the poles, the nuclear envelope reforms, and the cytoplasm divides, forming four daughter cells.
