9th Class Biology Chapter Wise Test Chapter 1 covers the complete first chapter of Biology, The Science of Biology, 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 1 Covers
This test paper is set on the whole of Chapter 1, The Science of Biology, 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 branches of biology — zoology, botany, microbiology, genetics, physiology, anatomy and ecology, and the kind of question each one answers.
- The levels of biological organisation, from the atom and molecule up through cell, tissue, organ, organ system, individual, population, community and biosphere.
- The biological method — observation, hypothesis, deduction, experiment, result, and the difference between a theory and a law.
- What makes a hypothesis scientific, and why an idea that cannot be tested is not one.
- The contribution of Muslim scientists to biology and medicine, including Jabir bin Hayyan, Bu Ali Sina and Abdul Malik Asmai.
- Careers in biology and how biology connects to the other sciences, giving fields such as biochemistry, biophysics and biotechnology.
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:
- The biological method begins with observation, not with the experiment. The experiment comes only after a hypothesis exists to test.
- A hypothesis must be testable and capable of being proved wrong. A theory is a hypothesis supported by a large body of evidence, and a law states a relationship confirmed repeatedly.
- Learn the levels of organisation in order — questions in this chapter often give you two levels and ask which comes between them.
- Bu Ali Sina wrote Al-Qanun fi al-Tibb, which was used as a medical text for centuries.
- Biology is the study of living things, so every definition you give should mention life or living organisms explicitly.
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:
- Starting the biological method with the experiment instead of with observation.
- Treating a theory as a guess, when in biology a theory is a well-supported explanation.
- Listing the levels of organisation out of order, especially around tissue, organ and organ system.
- Confusing anatomy with physiology — anatomy is structure, physiology is function.
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 1 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 first step of the biological method?
Observation. You notice something about a living organism, and that observation raises the question that your hypothesis then tries to answer.
What is the difference between a theory and a law in biology?
A theory is a well-tested explanation supported by a great deal of evidence and able to predict new results. A law states a relationship that experiments have confirmed over and over again. A theory does not become a law simply by getting older.
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.
