3 Days Study Plan: Cell Cycle & Cell Division | Biology Class 11 - NEET PDF Download

Let's explore the Biology chapter called "Cell Cycle and Divison" and how it's important for the NEET exam. By studying the past years NEET questions (from 2016 to 2024), we can see that this chapter is really important in the exam. If you want to score well in NEET, you need to understand the concepts  and Weightage of this chapter is 8%.

FAQs on 3 Days Study Plan: Cell Cycle & Cell Division - Biology Class 11 - NEET

1. What are the main phases of the cell cycle?
Ans.The cell cycle consists of four main phases: G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis). In the G1 phase, the cell grows and performs its normal functions. During the S phase, DNA is replicated to prepare for cell division. The G2 phase involves further growth and preparation for mitosis. Finally, in the M phase, the cell divides into two daughter cells.
2. How does the cell cycle control system regulate the process of cell division?
Ans.The cell cycle control system is regulated by a series of checkpoints that ensure the cell is ready to proceed to the next phase. Key proteins called cyclins and cyclin-dependent kinases (CDKs) work together to control the progression of the cell cycle. Checkpoints occur at G1, G2, and M phases to prevent errors such as DNA damage or incomplete replication from leading to cell division.
3. What is the difference between mitosis and meiosis?
Ans.Mitosis is the process of cell division that results in two genetically identical daughter cells, maintaining the same chromosome number as the parent cell. It consists of one division cycle. In contrast, meiosis is a specialized type of cell division that reduces the chromosome number by half, producing four genetically diverse gametes (sperm or eggs) through two rounds of division. This process is essential for sexual reproduction.
4. What role do checkpoints play in the cell cycle?
Ans.Checkpoints are critical control mechanisms in the cell cycle that ensure proper division. They monitor the integrity of DNA and the completion of critical processes before allowing the cell to progress. For instance, the G1 checkpoint checks for DNA damage and cell size, the G2 checkpoint verifies DNA replication, and the M checkpoint ensures that all chromosomes are properly attached to the spindle apparatus before division occurs.
5. How do cancer cells relate to the cell cycle?
Ans.Cancer cells often exhibit uncontrolled cell division due to mutations in genes that regulate the cell cycle. These mutations can lead to the bypass of checkpoints, allowing cells to proliferate excessively. Unlike normal cells, which respond to signals to stop dividing, cancer cells can continue to divide uncontrollably, leading to tumor formation and the spread of cancer throughout the body.
