Cell Cycle and Cell Division Assignments/DPPs

The captivating journey through the cell continues with the intricate process of cell division, explored in the chapter “Cell Cycle and Cell Division” for Class 11. This chapter equips you with a vital foundation for success in NEET and beyond. It unveils the remarkable choreography by which cells grow, replicate their genetic material, and divide to produce daughter cells, ensuring the continuity of life.

Overview : Cell Cycle and Cell Division for Class 11 and NEET

The life of a cell is a continuous cycle of growth, preparation for division, and division itself. This cyclical process is called the cell cycle and can be broadly divided into two main phases:

  • Interphase: The longest phase, accounting for 90% of the cell cycle. During interphase, the cell grows, replicates its DNA, and prepares for cell division. Interphase itself can be further subdivided into three stages:
    • G1 phase (Gap 1): The cell grows in size and carries out its regular functions.
    • S phase (Synthesis): DNA replication takes place, creating an exact copy of the cell’s genetic material.
    • G2 phase (Gap 2): The cell prepares for mitosis by synthesizing proteins and organelles needed for cell division.

  • M phase (Mitosis): The phase of actual cell division, where the replicated DNA condenses, chromosomes form, and the cell divides to produce two daughter cells with identical genetic material. Mitosis can be further subdivided into several sub-phases:
    • Prophase: Chromosomes condense, the nuclear envelope breaks down, and the mitotic spindle begins to form.
    • Prometaphase: Spindle fibers attach to the chromosomes.
    • Metaphase: Chromosomes align at the equator of the dividing cell.
    • Anaphase: Sister chromatids separate and move towards opposite poles of the cell.
    • Telophase: Nuclear envelopes reform around the separated chromosomes, and the cell begins to physically divide into two daughter cells.

Understanding Cell Division:

“Cell Cycle and Cell Division” delves deeper into the significance of cell division:

  • Growth and Repair: Cell division allows organisms to grow, develop, and repair damaged tissues.
  • Reproduction: Cell division is the foundation of asexual reproduction in single-celled organisms and the production of gametes (sex cells) in multicellular organisms.
  • Maintaining Chromosomal Number: Mitosis ensures that each daughter cell receives a complete and identical set of chromosomes.

Beyond Mitosis: Exploring Meiosis:

The chapter briefly introduces meiosis, a specialized type of cell division that occurs during sexual reproduction. Meiosis results in the formation of four haploid (half the number of chromosomes) daughter cells from a single diploid (full set of chromosomes) parent cell. This reduction in chromosome number is crucial for sexual reproduction, ensuring genetic diversity in the offspring.

Mastering Cell Cycle and Cell Division for NEET Success:

Conquering the intricacies of “Cell Cycle and Cell Division” empowers you to excel in NEET. Here’s how:

  • Focused assignments: Solidify your understanding by tackling dedicated exercises from PRERNA EDUCATION, focusing on specific topics like the phases of the cell cycle, the events of mitosis, the significance of cell division, and the differences between mitosis and meiosis.
  • Daily Practice Problems (DPPs): Hone your problem-solving skills and build speed by tackling daily practice problems (DPPs) encompassing diverse concepts like interpreting cell cycle diagrams, identifying phases of mitosis based on cell structures, and solving problems related to chromosome number inheritance.
  • Visualization and Mnemonics: Utilize labeled diagrams and flowcharts to visualize the stages of the cell cycle and mitosis. Employ memory aids like mnemonics to recall the sequence of events in mitosis (e.g., PMAT for Prophase, Metaphase, Anaphase, Telophase).
  • Connect to real-world applications: Foster a deeper appreciation for cell division by exploring its relevance in various fields, including medicine (understanding uncontrolled cell division in cancer) and biotechnology (developing techniques for genetic manipulation).


The “Cell Cycle and Cell Division” chapter unveils the remarkable process by which cells grow, replicate their DNA, and divide to ensure life’s continuity. Understanding the intricate dance of the cell cycle and the different types of cell division equips you with a crucial foundation for success in NEET and beyond.

Question Types:

NEET may include various question formats related to cell cycle and cell division, such as:

  • Matching phases of the cell cycle with their descriptions
  • Identifying structures observed during different stages of mitosis
  • Analyzing diagrams and interpreting cell division processes
  • Solving problems related to chromosome number inheritance in mitosis and meiosis
