9th Class Biology Chapter Wise Test Chapter 4

9th Class Biology Chapter Wise Test Chapter 4 covers the complete chapter of Biology, Cell Cycle, in a 36-mark bilingual paper with every question given in both English and Urdu. It follows the board pattern: ten MCQs with a bubble sheet, ten short questions of which any eight are attempted, and two detailed questions. An answer key for the MCQs is included at the end.

What Chapter 4 Covers

This test paper is set on the whole of Chapter 4, Cell Cycle, rather than a single exercise, so it is a fair check of whether the chapter is actually finished. The questions are drawn from across these topics:

• The cell cycle and its two main parts, interphase and the M phase.
• The sub-stages of interphase — G1, S and G2 — and what happens in each, particularly DNA replication in the S phase.
• Mitosis in order: prophase, metaphase, anaphase and telophase, with the key event of each.
• Cytokinesis, and how it differs between plant and animal cells.
• Meiosis I and meiosis II, crossing over, and why meiosis produces four haploid cells.
• The significance of mitosis and meiosis, and abnormalities of the cell cycle including cancer, apoptosis and necrosis.

Revise These Before You Attempt It

Most marks in this chapter are lost on the same handful of points. Read through these once before you start:

• DNA replicates during the S phase of interphase, not during mitosis itself.
• Remember the order of mitosis with the chromosome position: they condense in prophase, line up at the equator in metaphase, separate in anaphase, and new nuclei form in telophase.
• Mitosis produces two genetically identical diploid cells. Meiosis produces four genetically different haploid cells.
• Crossing over happens in prophase I of meiosis and is the main source of genetic variation.
• Apoptosis is programmed, controlled cell death; necrosis is unplanned cell death caused by injury.

How This Test Paper Is Built

The paper follows the board pattern for a chapter test rather than inventing its own, so sitting it is useful practice for the real thing:

• 36 marks in total, enough for a full class test.
• Ten multiple-choice questions with a bubble sheet to fill, exactly as in the board objective paper.
• Ten short questions, of which you attempt any eight.
• Two detailed questions carrying the longer written answers.
• Bilingual throughout — every question is printed in English and in Urdu, so both mediums use the same file.
• An MCQ answer key is included at the end of the paper.

Mistakes Students Make in This Chapter

When you mark your paper, check whether any of your lost marks came from these:

• Saying DNA replicates during prophase rather than during the S phase.
• Giving mitosis four daughter cells instead of two.
• Placing crossing over in mitosis, where it does not occur.
• Confusing apoptosis with necrosis.

After You Finish

Mark the objective section against the key at the end of the paper first, then mark the written sections against your textbook. Write down the topic behind every question you got wrong rather than just the question number, because it is the topic you need to revise, not the single question. If you want the same chapter marked for you automatically, take the Chapter 4 online test linked below: it shows the correct option and an explanation under every question the moment you submit, which is the quickest way to find out whether the gap has actually closed.

Frequently Asked Questions

What is the difference between mitosis and meiosis?

Mitosis produces two diploid daughter cells genetically identical to the parent and is used for growth and repair. Meiosis produces four haploid cells that differ genetically, and is used to make gametes.

When does DNA replication take place?

During the S phase of interphase, before mitosis begins. By the time prophase starts, each chromosome already consists of two sister chromatids.

Is this test paper free?

Yes. The PDF is free to download and print, there is no sign-up, and the MCQ answer key is included in the file.

Is it available in Urdu medium?

Yes. Every question in the paper is printed in English and in Urdu, so Urdu medium and English medium students download exactly the same file.
