Introduction
Cell division is a fundamental process in biology. It allows organisms to grow, repair themselves, and reproduce. There are two main types of cell division: meiosis and mitosis. Meiosis is used to produce gametes, or sex cells, while mitosis is used to produce new body cells.
Quiz
- Which type of cell division produces gametes?
- How many daughter cells are produced by meiosis?
- What is the difference between a haploid cell and a diploid cell?
- Which stage of meiosis is known as “crossing over”?
- Which stage of mitosis is known as “telophase”?
Answers
- Meiosis
- Four
- A haploid cell has one set of chromosomes, while a diploid cell has two sets.
- Prophase I
- Telophase
Meiosis vs. Mitosis
| Feature | Meiosis | Mitosis |
|---|---|---|
| Purpose | Produce gametes | Produce new body cells |
| Number of daughter cells | Four | Two |
| Chromosome number | Haploid (n) | Diploid (2n) |
| Crossing over | Yes | No |
| Used in | Reproduction | Growth and repair |
Applications of Meiosis and Mitosis
Meiosis has a number of important applications in medicine and agriculture. For example, meiosis can be used to:
- Create genetically modified crops
- Diagnose genetic diseases
- Develop new treatments for cancer
Mitosis has a number of important applications in medicine and agriculture as well. For example, mitosis can be used to:
- Grow new organs and tissues
- Treat wounds
- Clone animals
