What is the NCERT Exemplar Class 10 Science Book?
The NCERT Exemplar Class 10 Science is an extra problem book by NCERT, separate from your textbook. It carries tougher, thought-based questions. For Chapter 5, it tests how well you understand life processes like nutrition, respiration, transportation, and excretion, not just a definition.
- Made by NCERT: the language and level match your CBSE Class 10 syllabus 2026-27.
- Higher-order thinking: questions give you a situation, diagram, or process and ask you to reason, not recall.
- Board and beyond: many CBSE board and school test questions follow this style.
- Free and official: the PDF on this page is the real NCERT book.

What is Inside Chapter 5 of the NCERT Exemplar Class 10 Science
Chapter 5 of the Exemplar opens with multiple choice questions, then moves to short and long answer questions. Many are built around a process or pathway, so you practise both the biology and the skill of tracing the path of food, air, blood, or urine through the body. The table below shows the layout.
| Section | What it tests | Sample idea from Chapter 5 |
|---|---|---|
| Multiple Choice Questions | Quick concept checks with one or more correct options | Picking the correct sequence of parts in the human alimentary canal |
| Short Answer Questions | Two to three line answers with a reason | How guard cells regulate the opening and closing of stomatal pores |
| Long Answer Questions | Full answers with diagrams, pathways, and explanation | Explaining why blood circulation in humans is called double circulation |
Across these sections you meet the big ideas: autotrophic and heterotrophic nutrition, photosynthesis, digestion, aerobic and anaerobic respiration, transport through the heart and blood vessels, transport in plants, and excretion by the nephron. Many questions also bring in enzymes, stomata, double circulation, and the kidney, all CBSE favourites.
Question Types in the NCERT Exemplar Class 10 Science Chapter 5
Knowing the question types helps you plan your practice. The Exemplar uses a few clear formats, and each trains a skill you need for the CBSE board exam 2026-27.
- Single-correct MCQs: one option is right, testing a single idea like the filtration units of kidneys or the source of oxygen in photosynthesis.
- Multiple-correct MCQs: two or more statements are correct, so you pick the right combination, like true statements about the heart or respiration.
- Sequence and pathway MCQs: you order a process correctly, like the path of air during inhalation or urine in the body.
- Short answer (SA): two to three lines with a reason, good for "why does this happen" questions on emulsification or breathing rate.
- Long answer (LA): you draw a diagram and explain each step. These carry the most marks.
Why Solve the NCERT Exemplar for Chapter 5 Life Processes
The textbook teaches the chapter; the Exemplar tests whether you can use it. Solving it for Life Processes is one of the surest ways to lift your Science score, since the questions match the toughest board and school questions.
- You master the four life processes as a set. Tracing each process end to end is the most-tested skill here.
- You learn diagrams that score marks. The human heart, the nephron, and the digestive system appear again and again, so labelled-diagram practice pays off.
- You handle process logic with confidence. Questions cover aerobic versus anaerobic respiration, double circulation, and the role of enzymes.
- You meet real-life examples. Cramps after exercise, fish breathing in water, and the effect of dust on stomata all appear, linking the chapter to daily life.

How to Use the NCERT Exemplar Class 10 Science Chapter 5 PDF
The Exemplar works best as a practice book, not a reading book. A simple three-step routine keeps your study focused before the 2026-27 board exam.
- Step 1, learn first. Finish the chapter in your textbook and Notes so you know nutrition, photosynthesis, respiration, transportation, and excretion.
- Step 2, attempt on your own. Try the MCQs first, then short answers, then long answers. Draw every diagram by hand.
- Step 3, check and fix. Compare with the Exemplar Solutions page. Mark every wrong question and redo it the next day.
Topics Covered in NCERT Exemplar Class 10 Science Chapter 5
Every question sits on one of a small set of core ideas. If you are clear on the points below, you can attempt the whole chapter. The list also works as a quick revision checklist for the 2026-27 session.
| Topic | What you must know |
|---|---|
| Autotrophic and heterotrophic nutrition | Autotrophs make their own food; heterotrophs depend on others; parasitic and saprophytic modes |
| Photosynthesis | The summary equation, role of chlorophyll and sunlight, and that oxygen comes from water |
| Stomata and guard cells | How guard cells open and close the stomatal pore using water, controlling gas exchange |
| Human digestive system | The order of the alimentary canal, the role of saliva, HCl, mucus, bile, and pancreatic juice |
| Enzymes in digestion | Amylase on starch, pepsin and trypsin on proteins, lipase on emulsified fats |
| Aerobic and anaerobic respiration | Glucose to pyruvate in the cytoplasm, then the aerobic and yeast and muscle pathways |
| Human respiratory system | The path of air during inhalation and gas exchange in the alveoli of the lungs |
| The heart and double circulation | Four chambers, valves, arteries and veins, and why blood passes through the heart twice |
| Transport in plants | Xylem carries water and minerals; phloem carries food by translocation |
| Excretion and the nephron | The kidney, the nephron as the filtration unit, and the path of urine through the body |
Master these ten ideas and you can answer almost every Chapter 5 Exemplar question with confidence.
