Assertion and Reasoning Questions on Structure of Chromosome, Cell Cycle and Cell Division for ICSE Class 10 Biology
Assertion and reasoning questions are also known as assertion reason questions. Assertion-Reason questions are a type of question format used in ICSE exams where two statements are provided: an Assertion (A) and a Reason (R). Students need to determine whether each statement is true or false and if the Reason correctly explains the Assertion.
Q. 1. Assertion: Every chromosome, during metaphase has two chromatids.
Reason: Synthesis of DNA takes places in the S-phase of interphase.
(a) Both A and R are True.
(b) Both A and R are False.
(c) A is True and R is False.
(d) A is False and R is True.
Difficulty Level: Medium
Ans. (a) Both A and R are True.
Explanation:
During metaphase, every chromosome is made up of two identical strands called chromatids, which are the result of DNA replication during the S-phase (synthesis phase) of interphase. This replication ensures that each daughter cell will receive an identical set of chromosomes during cell division.
Q. 2. Assertion: In animal cells, cytokinesis is marked by the appearance of a furrow in plasma membrane.
Reason: In plant cells, the formation of the new cell wall starts with the formation of simple precursor called cell plate.
(a) Both A and R are True.
(b) Both A and R are False.
(c) A is True and R is False.
(d) R is False and A is True.
Difficulty Level: Medium
Ans. (a) Both A and R are True.
Explanation:
In animal cells, cytokinesis occurs as a furrow forms in the plasma membrane, which deepens to divide the cell into two. In contrast, plant cells undergo cytokinesis differently due to their rigid cell walls, with a cell plate forming at the cell’s equator and extending outwards to split the cell in two.
We hope the given ICSE assertion reasoning questions for Structure of Chromosome, Cell Cycle and Cell Division helps you in your learning.

- Understanding the phases of Mitosis, including the chromosome count in daughter cells post-Mitosis and Meiosis.
- Nuclear changes during Mitosis.
These are the topics from chapter Structure of Chromosome, Cell Cycle and Cell Division, generally found difficult by students studying in ICSE Class 10 Biology.
Common Errors Made by Students:
- The majority of students could identify the stages in mitotic cell division accurately but failed to provide a valid explanation.
- Several students did not depict the correct diagram of Telophase, lacking the depiction of daughter nuclei with nuclear membranes; some even mislabelled the nuclear membrane as the cell membrane.
- The majority were uncertain about the differences between plant cells and animal cells.
- Some students struggled with describing the arrangement pattern of chromosomes during cell division stages.
- A few students did not maintain the consistent chromosome count in the Anaphase diagram.
- Many students were unclear about the sequence of mitotic stages and frequently did not illustrate the accurate number of chromosomes.
- Numerous students had difficulty spelling ‘Mitosis’ and ‘Meiosis’ correctly.
- Many were confused between the ‘Anaphase’ and ‘Metaphase’ stages.
- There was widespread confusion regarding the number of daughter cells and their chromosome count.
- Some students were not aware about the difference between chromosome and chromatid.
Frequently Asked Questions (FAQs) on Structure of Chromosome, Cell Cycle and Cell Division ICSE Class 10 Biology Assertion and Reasoning Questions
Q1: What are Assertion and Reasoning questions?
A1: Assertion and Reasoning questions are a type of question format used in ICSE exams where two statements are provided: an Assertion (A) and a Reason (R). Students need to determine whether each statement is true or false and if the Reason correctly explains the Assertion.
Q2: How do Assertion Reasoning questions differ from other question types?
A2: Unlike multiple-choice questions, Assertion-Reason questions require students to analyze the relationship between two statements. It’s not just about knowing the facts but understanding how they connect logically.
Q3: What steps should I follow to correctly answer Assertion and Reasoning questions?
A3: Follow these steps:
Read both statements carefully. Understand what each statement is saying.
Determine the truth value of each statement. Decide if each statement is true or false independently.
Analyze the relationship. If both statements are true, decide whether the Reason (R) correctly explains the Assertion (A).
Choose the correct option. Based on your analysis, select the appropriate answer from the given options.
Q4: What options are typically provided for Assertion and Reasoning questions?
A4: The typical options are:
A. Both A and R are true, and R is the correct explanation of A.
B. Both A and R are true, but R is not the correct explanation of A.
C. A is true, but R is false.
D. A is false, but R is true.
Q5: What should I check to determine if the Reason correctly explains the Assertion?
A5: Ensure that the Reason provides a logical explanation for the Assertion. Check if the Reason directly addresses the cause or basis of the Assertion and if they are contextually linked.
Q6: How can I improve my skills in answering Assertion and Reasoning type questions?
A6: Practice regularly with sample questions and past papers. Focus on understanding the concepts thoroughly rather than rote memorization. Analyzing how different facts and concepts interrelate will enhance your ability to correctly answer these questions.
Q7: What are common mistakes to avoid when answering Assertion and Reasoning questions?
A7: Common mistakes include:
Not reading the statements carefully and missing key details.
Assuming the Reason explains the Assertion without checking the logical connection.
Confusing the order or relationship between the statements.
Overthinking and adding information not provided in the question.
Q8: What resources can help me practice Assertion and Reasoning questions for ICSE Class 10 Biology?
A8: Use study guides specifically designed for Assertion-Reason questions. Online educational platforms and reference books for ICSE Class 10 Chemistry also offer practice questions and explanations. xamcontent.com/cisce also provides assertion reason questions for ICSE Class 10 Biology.
