Chapter Overview and Marks Weightage in CBSE Exams

Transportation in Animals and Plants covers how nutrients, water, gases, and waste products move within living organisms. The NCERT Class 7 Science textbook divides the chapter into two broad themes: transport in animals (circulatory system, blood components, heart structure, and excretion) and transport in plants (xylem and phloem, transpiration, root pressure). In CBSE term exams, this chapter typically carries 5 to 7 marks. Expect one or two 1-mark MCQs testing recall of facts like the name of the fluid tissue or the vessel that carries oxygenated blood. A 2-mark question usually asks for a labelled diagram or a short comparison between arteries and veins. The 3-mark descriptive question probes processes such as how water travels from roots to leaves or the role of platelets in blood clotting. Finally, a 5-mark case-based or long-answer question may present a scenario—perhaps a child with anaemia or a potted plant wilting—and ask you to apply NCERT concepts to explain observations and suggest remedies. Many CBSE schools in Delhi, Mumbai, Bengaluru, and Kolkata set at least one diagram-labelling question from the heart or the excretory system, so diagram practice is non-negotiable for securing full marks.

Total expected weightage: 5-7 marks per term exam
1-mark MCQs on definitions, names of blood vessels, components of blood
2-mark questions on labelled diagrams or short comparisons (artery vs. vein, xylem vs. phloem)
3-mark questions on process descriptions: transpiration, excretion, double circulation
5-mark case-based or long-answer questions linking real-life scenarios to NCERT concepts

1-Mark Questions: MCQs and Very Short Answers

These questions test quick recall and conceptual clarity. CBSE examiners often pick statements straight from NCERT text or ask you to identify the correct term among four options. Focus on definitions, names of structures, and simple functions. Answers should be one word, one phrase, or a single sentence. Below are six representative 1-mark questions with model answers that reflect NCERT language. Practise these to build speed and accuracy, especially for objective-type assessments conducted by many CBSE-affiliated schools across India. Remember, even a small mistake—writing 'artery' instead of 'vein'—costs you the full mark, so read each option carefully during exams. These questions frequently appear in the first section of CBSE question papers and set the tone for your confidence in the rest of the paper.

Q1. Which blood vessel carries blood away from the heart? Answer: Artery
Q2. Name the liquid part of blood. Answer: Plasma
Q3. What is the term for loss of water vapour from plant leaves? Answer: Transpiration
Q4. Which tissue in plants transports food from leaves to other parts? Answer: Phloem
Q5. Name the pigment that gives red colour to blood. Answer: Haemoglobin
Q6. What are the tiny filters in kidneys called? Answer: Nephrons

2-Mark Questions with Model Answers

Two-mark questions demand concise explanations or simple comparisons. CBSE marking schemes award one mark for each correct point, so structure your answer in two clear sentences or a two-column table. Diagram-labelling questions are common here: you might be given an outline of the human heart or a cross-section of a plant stem and asked to label two or three parts. When comparing structures—such as arteries versus veins or xylem versus phloem—use a tabular format to earn both marks reliably. Avoid writing long paragraphs; examiners appreciate brevity and clarity. Below are four representative 2-mark questions with model answers that mirror NCERT terminology and CBSE expectations. Practise writing these answers within 2-3 minutes to simulate exam conditions, a skill that many students at schools in NCR and Bengaluru find crucial for time management.

3-Mark Questions with Detailed Answers

Three-mark questions require you to describe a process, explain a phenomenon, or draw and label a diagram with a short note. CBSE examiners allocate one mark per valid point or label, so aim for three distinct sentences or three correctly labelled parts. Popular topics include the pathway of blood through the heart (double circulation), the mechanism of transpiration, the structure and function of nephrons, and the role of xylem and phloem in plant transport. When drawing diagrams, use a sharp pencil, label neatly with arrow lines (not freehand scribbles), and write the names in block letters. Even if your drawing is not artistic, clear labels fetch full marks. Below are four carefully selected 3-mark questions with model answers that reflect NCERT language. These questions mirror the style seen in CBSE schools across Chennai, Pune, and Hyderabad, where diagram-based assessment is a staple of internal and term exams.

5-Mark Questions and Case-Based Problems

Five-mark questions test your ability to integrate multiple NCERT concepts and apply them to real-world or hypothetical scenarios. CBSE often presents a short case study—for example, a paragraph about a farmer noticing wilted crops despite regular watering, or a news snippet about rising heart disease in urban India—and asks three or four sub-questions. Alternatively, you may be asked to describe the complete pathway of blood circulation in humans, including both systemic and pulmonary circuits, and explain the role of valves. Mark allocation is usually distributed as 2+2+1 or 3+2, so read the question carefully to see how many points are expected for each part. Use subheadings or bullet points to organise your answer, making it easy for the examiner to award marks. Below are two representative 5-mark questions with structured model answers. These mirror the format used in CBSE sample papers and are similar to questions set by schools in Jaipur, Lucknow, and Ahmedabad during final term exams.

How CBSE Frames Questions from This Chapter

CBSE question-paper setters follow a predictable pattern for Transportation in Animals and Plants, drawing directly from NCERT text, in-text questions, and end-of-chapter exercises. Diagram-based questions are a staple: expect to label the human heart, a nephron, or a transverse section of a stem showing xylem and phloem. Process-oriented questions ask you to 'describe' or 'explain'—for example, 'Explain how the heart pumps blood' or 'Describe the pathway of water from soil to leaf'. Comparison questions are set as tables: 'Differentiate between arteries and veins' or 'Compare xylem and phloem'. Case-based questions, introduced widely after the 2020 curriculum update, present a short paragraph followed by sub-questions testing application, analysis, and evaluation skills. Recent CBSE sample papers have included scenarios like athletes' heart rates, effects of dehydration on excretion, and impact of air pollution on stomatal function. Assertion-Reason MCQs are also emerging in Class 7 internal assessments at many schools. To excel, read NCERT Chapter 7 thoroughly, underline key terms like 'haemoglobin', 'transpiration pull', 'nephron', and 'phloem', and practise writing answers in the exact language of the textbook. CBSE rewards precision and penalises vague or colloquial explanations.

Diagram labelling: heart, excretory system, xylem-phloem cross-section
Process descriptions: double circulation, transpiration, excretion
Comparison tables: artery vs. vein, xylem vs. phloem, atrium vs. ventricle
Case-based scenarios linking real-life observations to NCERT concepts
Assertion-Reason MCQs testing conceptual linkages
Application questions: Why do we feel thirsty after exercise? Why do plants droop in summer afternoon?

Common Mistakes Students Make in Exams

Even well-prepared students lose marks on this chapter due to recurring errors. One frequent mistake is confusing xylem with phloem: remember xylem transports water and minerals upward, while phloem transports food (sugars) in all directions. Another pitfall is mixing up the pulmonary and systemic circuits—write clearly which side of the heart handles oxygenated versus deoxygenated blood. When labelling the heart, students often mislabel the aorta as the pulmonary artery or forget to mark the valves. In questions on excretion, many write 'kidney removes waste' without naming the functional unit, the nephron, or explaining filtration. Diagram neatness matters: freehand scribbles or unlabelled arrows cost marks even if the structure is correct. Spelling errors like 'hoemoglobin' or 'transperation' can lose you a mark in strict CBSE checking. Time management is another issue—spending too long on a 5-mark question leaves no time for 1-mark MCQs that are easier to score. Finally, students often write long paragraphs for 2-mark questions when bullet points or a two-sentence answer would suffice. Practise past CBSE papers under timed conditions to avoid these traps, a strategy that top scorers in schools across Noida, Gurgaon, and Faridabad swear by.

Confusing xylem (water transport) with phloem (food transport)
Mixing up oxygenated and deoxygenated blood pathways in the heart
Mislabelling or omitting valves and chamber names in heart diagrams
Writing 'kidney' without mentioning nephrons in excretion answers
Untidy diagrams with unclear labels or missing arrow lines
Spelling errors: haemoglobin, transpiration, excretion, ventricle
Poor time management: spending too long on descriptive questions
Writing paragraphs instead of bullet points for 2-mark questions

Sample Case-Based Question with Detailed Solution

Case-based questions are now a regular feature in CBSE Class 7 Science assessments, aligning with the NEP 2020 focus on application and critical thinking. Below is a complete worked example that illustrates how to approach such questions. Read the passage carefully, underline key facts, and map them to NCERT concepts before attempting the sub-questions. Marks are awarded for correct identification of concepts, logical reasoning, and use of scientific terminology. This format is increasingly common in schools across metropolitan cities and Tier-2 towns alike, so practising case studies is essential for scoring above ninety percent in Science.

Diagram Practice: Must-Know Diagrams for Full Marks

Diagrams carry significant weightage in CBSE Class 7 Science Chapter 7 exams. A well-labelled diagram can fetch 3 marks in one go, while a poorly drawn or unlabelled sketch earns zero. Focus on three core diagrams: the structure of the human heart (four chambers, major vessels, valves), the excretory system (kidneys, ureters, bladder, urethra), and a transverse section of a plant stem showing xylem and phloem arrangement. Use a sharp HB pencil for outlines and a pen for labels. Draw diagrams large enough to label clearly—tiny sketches crammed into a corner are hard to mark. Each label should have a neat arrow pointing precisely to the structure, not hovering in empty space. Write labels in capital letters or clear print; cursive handwriting can be misread. Practise these diagrams daily for a week before the exam, timing yourself to complete each in under three minutes. Many CBSE schools in Kolkata, Patna, and Bhopal set aside marks exclusively for diagram accuracy, so this practice directly translates into score gains.

Human heart: label left atrium, left ventricle, right atrium, right ventricle, aorta, pulmonary artery, pulmonary vein, vena cava, valves
Excretory system: label kidneys, ureters, urinary bladder, urethra
Transverse section of stem: label epidermis, cortex, xylem, phloem, vascular bundle, pith
Use sharp pencil for outlines, pen for labels; draw large and neat
Arrow lines must point exactly to the structure, not float nearby
Write labels in block letters or clear print to avoid examiner confusion
Practise each diagram under timed conditions—aim for completion in 2-3 minutes

Frequently asked questions

How many marks does Chapter 7 Transportation in Animals and Plants carry in CBSE Class 7 Science term exams?+

This chapter typically carries 5 to 7 marks in CBSE Class 7 Science term exams. Expect one or two 1-mark MCQs, one 2-mark question (often a diagram or comparison), one 3-mark descriptive question, and sometimes a 5-mark case-based or long-answer question.

What are the most important diagrams to practise for Chapter 7 exams?+

Focus on three diagrams: the structure of the human heart with all four chambers and major blood vessels labelled, the human excretory system showing kidneys, ureters, bladder, and urethra, and a transverse section of a plant stem highlighting xylem and phloem arrangement. These diagrams appear almost every year in CBSE question papers.

How should I differentiate between xylem and phloem in a 2-mark question?+

Write two clear points in tabular or bullet form: (i) Xylem transports water and minerals from roots upward; phloem transports food (sugars) from leaves to all parts in all directions. (ii) Xylem consists of dead cells; phloem consists of living cells. This structure ensures you earn both marks.

What is double circulation, and why is it important?+

Double circulation means blood passes through the heart twice in one complete cycle: once through the lungs (pulmonary circulation) to get oxygenated, and once through the body (systemic circulation) to deliver oxygen. This prevents mixing of oxygenated and deoxygenated blood, ensuring efficient oxygen supply to tissues in mammals.

Why do CBSE examiners frequently ask about transpiration?+

Transpiration is central to water transport in plants and links multiple concepts: loss of water vapour, suction pull, cooling effect, and mineral distribution. CBSE values process-based understanding, so questions like 'Explain the role of transpiration in water movement' test whether students grasp cause-and-effect relationships beyond rote memorisation.

How can I avoid losing marks on diagram labelling?+

Use a sharp pencil for outlines, draw diagrams large enough to label clearly, point arrows precisely to structures, and write labels in block letters or neat print. Avoid tiny sketches, floating arrows, or cursive handwriting. Practise each diagram at least five times before the exam to build speed and accuracy.

What common mistakes should I avoid in answers about the heart?+

Do not mix up the left and right sides—left side handles oxygenated blood, right side handles deoxygenated blood. Always mention the pulmonary artery carries deoxygenated blood to lungs and the pulmonary vein brings oxygenated blood back, exceptions to the general rule. Label valves correctly to show they prevent backflow between chambers.

Are case-based questions difficult in Chapter 7?+

Case-based questions test application rather than recall, but they draw entirely from NCERT concepts. Read the passage carefully, underline key facts, map them to topics like transpiration, excretion, or circulation, and answer sub-questions in clear points. Practising two or three sample case studies before the exam builds confidence and speed.
