UP Board Class 11 Biology – Cell Cycle and Cell Division

The chapter “Cell Cycle and Cell Division” in UP Board Class 11 Biology explores the processes by which cells grow, replicate, and divide to maintain life. It explains the cell cycle, including the interphase (G?, S, and G? phases) where the cell grows and DNA replicates, and the mitotic (M) phase, where actual division occurs.



Students learn about mitosis, the process of somatic cell division that ensures genetic continuity, and meiosis, the reductional division that produces gametes with half the chromosome number, enabling sexual reproduction. The chapter also covers significance of cell division, checkpoints, and regulation mechanisms that prevent uncontrolled growth.

Understanding the cell cycle and division is crucial for studying genetics, growth, development, and cancer biology. This chapter forms a strong foundation for higher studies in molecular biology, genetics, and competitive exams like NEET, CUET, and UP Board.
