What to expect: This mock test covers key concepts from the Cell Cycle and Structure of Chromosomes chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.What is the role of the endoplasmic reticulum (ER) in a cell?
- A.It provides structural support and synthesizes proteins and lipids for transport within the cell.
- B.It breaks down waste materials and recycles cellular components through digestion.
- C.It stores genetic information and regulates cell division through chromosome formation.
- D.It generates energy in the form of ATP through cellular respiration processes.
-
2.What are the repeating components that make up the length of each DNA strand?
- A.Ribonucleotide
- B.Amino acid
- C.Deoxyribonucleotide
- D.Nitrogenous base
-
3.Which type of cell division takes place in reproductive tissues?
- A.Meiosis
- B.Mitosis
- C.Binary fission
- D.Amitosis
-
4.What is the difference between chromatin fibre and chromosome in terms of their structure and visibility during the cell cycle?
- A.Chromatin fibre is highly condensed and visible during cell division, while chromosomes are loose and visible during interphase.
- B.Chromatin fibre is a long, thin, loosely coiled network of DNA and proteins visible during interphase, while chromosomes are condensed structures formed from chromatin fibres during cell division.
- C.Chromatin fibre and chromosomes are identical in structure but differ only in their location within the cell.
- D.Chromosomes are always visible, while chromatin fibres are never visible under a microscope.
-
5.What are the two main divisions that occur during cell division?
- A.Karyokinesis and cytokinesis
- B.Mitosis and meiosis
- C.Prophase and metaphase
- D.Interphase and anaphase
