FAQs on Why cell division Video Lecture - NEET
| 1. What is cell division? |  |
Ans. Cell division is the process by which a parent cell divides into two or more daughter cells. It is a vital process for growth, repair, and reproduction in living organisms. During cell division, the genetic material is evenly distributed between the daughter cells, ensuring the continuity of life.
| 2. What are the two main types of cell division? | |
Ans. The two main types of cell division are mitosis and meiosis. Mitosis is a type of cell division that produces two genetically identical daughter cells, each having the same number of chromosomes as the parent cell. It plays a crucial role in growth, repair, and asexual reproduction. Meiosis, on the other hand, is a specialized type of cell division that occurs in the reproductive cells. It results in the formation of four daughter cells, each with half the number of chromosomes as the parent cell, and is essential for sexual reproduction.
| 3. How does cell division contribute to growth? | |
Ans. Cell division is responsible for the growth and development of multicellular organisms. Through mitosis, cells divide and increase in number, leading to the growth of tissues, organs, and ultimately the entire organism. During growth, cells divide and differentiate into specialized cell types, forming various tissues and organs. By continuously dividing and differentiating, cells contribute to the overall growth and development of an organism.
| 4. What happens if cell division is not properly regulated? | |
Ans. Proper regulation of cell division is crucial for maintaining the balance between cell growth and cell death. If cell division is not properly regulated, it can lead to various abnormalities and diseases. Uncontrolled cell division can result in the formation of tumors, which may be benign or malignant. Benign tumors are non-cancerous and do not spread to other parts of the body, while malignant tumors are cancerous and can invade nearby tissues and spread to distant sites, causing serious health issues.
| 5. How is cell division related to the NEET exam? | |
Ans. Cell division is an important topic in biology, and understanding its mechanisms and significance is essential for NEET exam preparation. Questions related to cell division often appear in the NEET exam, as it assesses the students' knowledge of fundamental biological processes. Candidates are expected to have a clear understanding of mitosis, meiosis, and their significance in growth, development, and reproduction. Studying cell division thoroughly will help students perform well in the NEET exam's biology section.
