FAQs on Mitosis Video Lecture - Biology for GCSE/IGCSE - Year 11
| 1. What is mitosis? |  |
Ans. Mitosis is a process in which a single cell divides into two identical daughter cells, each with the same number of chromosomes as the parent cell.
| 2. Why is mitosis important for living organisms? | |
Ans. Mitosis is essential for growth, repair, and asexual reproduction in living organisms. It ensures that each new cell receives the correct number of chromosomes and genetic material.
| 3. What are the stages of mitosis? | |
Ans. The stages of mitosis are prophase, metaphase, anaphase, and telophase. During prophase, the chromosomes condense. In metaphase, the chromosomes line up at the center of the cell. Anaphase is when the chromosomes separate and move to opposite ends of the cell. Telophase is the final stage where the cell divides into two daughter cells.
| 4. How does mitosis differ from meiosis? | |
Ans. Mitosis results in two identical daughter cells with the same number of chromosomes as the parent cell. Meiosis, on the other hand, is a process that produces four genetically different daughter cells with half the number of chromosomes as the parent cell. Meiosis is involved in sexual reproduction.
| 5. What can go wrong during mitosis? | |
Ans. Errors during mitosis can lead to genetic abnormalities, such as aneuploidy, where cells have an abnormal number of chromosomes. These abnormalities can result in birth defects, developmental disorders, or even cancer.
