Cell Cycle and Cell Division Important Questions for NEET 2025

Cell Cycle and Cell Division Important Questions for NEET: Cell Cycle and Cell Division is a crucial topic in the NEET Biology syllabus. This topic forms the foundation of cell biology and includes key concepts such as mitosis, meiosis, and the phases of the cell cycle. Understanding this topic is essential for NEET 2025 Exam as it frequently appears in the examination with both direct and conceptual questions. Understanding these concepts not only helps in scoring well but also improves the understanding of related topics like genetics, molecular biology, and developmental biology.

Cell Cycle and Cell Division Important Questions for NEET

The Cell Cycle and Cell Division is a fundamental concept in biology that explains how cells grow, replicate, and divide. It plays a crucial role in the continuity of life, ensuring genetic material is accurately passed from one generation to the next. This topic is central to the NEET syllabus as it provides the foundation for understanding processes like growth, repair, reproduction, and genetic inheritance.

What is Cell Cycle and Cell Division?

• G1 Phase: Cell growth and preparation for DNA replication.
• S Phase: DNA synthesis and replication.
• G2 Phase: Final growth and preparation for mitosis.
• M Phase (Mitosis): The phase where actual cell division occurs, resulting in two genetically identical daughter cells.

• Mitosis: Produces two identical diploid cells, crucial for growth and repair.
• Meiosis: Results in four haploid cells, essential for sexual reproduction and maintaining genetic diversity.
