* Mitosis: This is the process by which most cells in the body divide to produce two identical daughter cells. This is used for growth, repair, and replacement of old or damaged cells.
* Meiosis: This is a specialized type of cell division that occurs only in the reproductive cells (sperm and egg). It produces four daughter cells, each with half the number of chromosomes as the parent cell. This process is essential for sexual reproduction.
The process of cell division involves several steps:
1. Interphase: This is the longest phase of the cell cycle, during which the cell grows, copies its DNA, and prepares for division.
2. Prophase: The chromosomes condense and become visible.
3. Metaphase: The chromosomes line up in the middle of the cell.
4. Anaphase: The sister chromatids (identical copies of a chromosome) separate and move to opposite poles of the cell.
5. Telophase: The chromosomes reach the poles of the cell, the nuclear envelope reforms, and the cytoplasm divides, forming two daughter cells.
So, in short, new cells are formed through cell division, which involves the duplication of the cell's DNA and the division of the cytoplasm.
