Cell Cycle and Cell Division Topic-wise Multiple Choice Questions (MCQs) for NEET Preparation | Topic-wise MCQ Tests for NEET PDF Download

In order to be admitted to undergraduate medical programmes, you must pass the NEET, or National Eligibility cum Entrance Test. The 180 questions in NEET-UG are broken down into three sections: Physics (45 questions), Chemistry (45 questions), and Biology (90 questions). It indicates that the Biology portion has a higher weight than the other two areas.
One of the smart techniques to prepare for the NEET biology exam is to know about the topic-wise important questions from each chapter. To highlight this, the experts at EduRev have compiled tests from most important topics of biology Multiple choice questions (MCQs) for your practice. These topic-wise multiple choice questions (MCQs) tests are made precisely from NCERT and some of them have even been asked in previous year NEET papers.
The below given topic-wise Multiple choice questions (MCQs) tests are from the Cell cycle and cell division chapter of Class 11 biology for your NEET preparation.

Please note that 10%-20% of the above-mentioned tests are free while others are locked and can be accessed by subscribing to the EduRev Infinity package for NEET.

FAQs on Cell Cycle and Cell Division Topic-wise Multiple Choice Questions (MCQs) for NEET Preparation - Topic-wise MCQ Tests for NEET

1. What is the cell cycle and why is it important in cell division?
The cell cycle refers to the series of events that take place in a cell leading to its division and duplication. It consists of interphase (G1, S, and G2 phases) and mitotic phase (mitosis and cytokinesis). The cell cycle is essential for growth, development, tissue repair, and reproduction in multicellular organisms.
2. What are the phases of the cell cycle?
The cell cycle consists of interphase and the mitotic phase. Interphase is further divided into three phases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2). The mitotic phase includes mitosis (nuclear division) and cytokinesis (cytoplasmic division).
3. What happens during the S phase of the cell cycle?
During the S phase of the cell cycle, DNA replication takes place. The DNA molecule unwinds, and each strand serves as a template for the synthesis of a new complementary strand. This results in the formation of two identical copies of the DNA molecule, called sister chromatids, which are held together by a centromere.
4. What is mitosis and what are its stages?
Mitosis is the process of nuclear division in which one cell nucleus divides into two genetically identical daughter nuclei. It consists of four stages: prophase, metaphase, anaphase, and telophase. During prophase, chromatin condenses into chromosomes, the nuclear envelope breaks down, and spindle fibers form. In metaphase, chromosomes align along the equator of the cell. Anaphase involves the separation of sister chromatids, which move towards opposite poles of the cell. In telophase, the nuclear envelopes reform, chromosomes decondense, and the cell prepares for cytokinesis.
5. What is the significance of cell division in multicellular organisms?
Cell division plays a crucial role in multicellular organisms. It allows for growth and development by increasing the number of cells. It is responsible for tissue repair and regeneration. During reproduction, cell division is involved in the formation of gametes (sperm and egg cells) and the development of a new organism from a fertilized egg. Additionally, cell division ensures the maintenance of a constant number of chromosomes in each generation.
