Quick Chapter Recap - Transportation in Animals and Plants

Before attempting the worksheet, review these core concepts from NCERT Class 7 Science Chapter 7. The circulatory system in humans consists of the heart, blood, and blood vessels (arteries, veins, capillaries). Blood comprises plasma, red blood cells (RBCs), white blood cells (WBCs), and platelets. The human heart has four chambers — two atria and two ventricles — working in a coordinated manner to pump blood throughout the body. Excretion removes metabolic waste; kidneys filter blood to produce urine, which is stored in the urinary bladder. In plants, xylem transports water and minerals from roots to leaves, while phloem distributes food prepared in leaves to all plant parts. Transpiration, the loss of water vapour through stomata, creates a suction pull that aids upward water movement.

Circulatory system: Heart (4 chambers), blood (plasma, RBCs, WBCs, platelets), blood vessels (arteries, veins, capillaries)
Arteries carry oxygenated blood away from heart; veins bring deoxygenated blood back; capillaries enable exchange
Excretory system: Kidneys filter blood, ureters transport urine, urinary bladder stores it, urethra expels it
Xylem: Dead tubular cells transport water and minerals upward through roots, stem to leaves
Phloem: Living cells transport food (sugars) from leaves to all plant parts in both directions
Transpiration pull and root pressure help water ascent in tall plants

Section A: Multiple Choice Questions (MCQs)

Choose the correct option for each question. Each MCQ carries 1 mark. These questions test your recall and understanding of the circulatory system, blood components, excretion, and plant transport systems. Read each option carefully before selecting your answer. In the 2024 CBSE Class 7 Science exam pattern, objective questions form about 30-40 percent of the paper, making MCQ practice essential. Cover the answers column and attempt all questions independently first. Check the detailed answer key at the end to verify your responses and understand any mistakes. Some questions require you to eliminate wrong options systematically, a crucial skill for competitive exams later. Focus especially on terminology like xylem, phloem, atria, ventricles, plasma, and transpiration as these appear frequently in board assessments and school tests across CBSE-affiliated institutions.

Q1. Which component of blood helps in clotting? (a) RBC (b) WBC (c) Platelets (d) Plasma
Q2. The chamber of heart that receives oxygenated blood from lungs is: (a) Right atrium (b) Left atrium (c) Right ventricle (d) Left ventricle
Q3. Xylem transports: (a) Food (b) Water and minerals (c) Hormones (d) Oxygen
Q4. The filtering units in kidneys are called: (a) Neurons (b) Nephrons (c) Ureter (d) Alveoli
Q5. Which blood vessels have valves? (a) Arteries (b) Veins (c) Capillaries (d) All of these
Q6. Phloem tissue is responsible for: (a) Water transport (b) Transpiration (c) Food transport (d) Gas exchange
Q7. Normal resting heartbeat in adults is about: (a) 50 bpm (b) 72 bpm (c) 100 bpm (d) 120 bpm
Q8. Loss of water as vapour from aerial parts of plant is: (a) Evaporation (b) Guttation (c) Transpiration (d) Respiration

Section B: Fill in the Blanks

Complete each sentence with the appropriate scientific term from Chapter 7. Each blank carries 1 mark. Pay attention to spelling, as incorrect spellings may not fetch full marks in school exams. Use exact NCERT terminology wherever possible. This section reinforces vocabulary and concept linkages critical for Class 7 Science notes and exam success. Words like haemoglobin, atrium, urinary bladder, vascular bundles, and stomata are commonly tested. The CBSE marking scheme typically awards marks only when the precise term is used, not synonyms. For example, 'blood purification organ' will not earn marks if the answer expected is 'kidney'. Practice writing these terms multiple times to build muscle memory and ensure you recall them accurately under exam pressure during your school's periodic tests and annual examinations.

Q9. The red pigment in RBCs that carries oxygen is __________.
Q10. Arteries have __________ walls compared to veins.
Q11. The tube that carries urine from kidney to urinary bladder is called __________.
Q12. The tissue that transports food in plants is __________.
Q13. The upper chambers of the heart are called __________.
Q14. Small pores on the leaf surface through which transpiration occurs are __________.
Q15. The liquid part of blood is called __________.
Q16. In plants, root pressure and __________ pull help in upward movement of water.

Section C: True or False Statements

Write True or False for each statement. If false, write the correct statement in brackets. Each question carries 1 mark. This section sharpens your ability to identify factual accuracy, a skill tested in CBSE Class 7 Science examinations and Olympiads. Read each statement twice before deciding. A single incorrect word can make an otherwise accurate statement false. For instance, saying xylem transports food instead of water makes the whole statement wrong. CBSE examiners often twist a small detail to test whether students have rote-learned or genuinely understood the concept. When correcting false statements, rewrite them completely and clearly rather than just negating them. This practice will help you in descriptive answer writing as well. Keep NCERT Class 7 Science definitions as your reference standard, because board exams follow NCERT language closely.

Q17. Veins carry oxygenated blood from heart to body parts.
Q18. White blood cells help fight infections in the body.
Q19. Phloem consists of dead tubular cells.
Q20. The heart of a fish has four chambers.
Q21. Excretion is the process of removing undigested food from the body.
Q22. Transpiration helps in cooling the plant and upward movement of water.
Q23. Capillaries have thick muscular walls.
Q24. The left ventricle pumps blood to the lungs.

Section D: Short Answer Questions (2-3 Marks Each)

Answer the following questions in 30-50 words each. These questions typically carry 2 or 3 marks in CBSE Class 7 Science examinations. Structure your answers in clear points or short paragraphs. Begin with a definition if asked, then add two or three supporting facts. Underline or highlight key terms like circulatory system, excretion, xylem, phloem, atria, ventricles to show the examiner you know the terminology. Use diagrams wherever possible; a labelled diagram of the heart or a cross-section of xylem and phloem can fetch you bonus marks and make your answer stand out. Time management is crucial: allocate about 3-4 minutes per short question. Practising these questions regularly will also strengthen your Class 7 Science notes and improve retention. Refer to NCERT solutions and sample papers to see model answers, and then try to write in your own words without copying verbatim.

Q25. What are the main components of blood? Write one function of each.
Q26. Differentiate between arteries and veins (any three points).
Q27. Explain the role of kidneys in excretion.
Q28. Describe the pathway of water from soil to leaves in a plant.
Q29. Why is transportation necessary in living organisms?
Q30. What is the function of valves in the heart and veins?
Q31. How does transpiration help plants?

Section E: Long Answer and HOTS Questions (5 Marks Each)

Answer the following questions in 80-120 words. Long-answer questions test your depth of understanding and ability to organize information logically. They typically carry 5 marks each in CBSE term exams. Start with an introduction, develop the body in 3-4 well-defined points, and conclude if necessary. Use subheadings, bullet points, or numbered lists to make your answer easy to read. Include a labelled diagram wherever the question allows—diagrams of the human heart, excretory system, or a cross-section showing xylem and phloem can earn you 1-2 additional marks. HOTS (Higher Order Thinking Skills) questions require application and analysis, not just recall. For example, explaining why desert plants have reduced transpiration connects biology to environmental adaptation. Spend about 6-7 minutes on each long answer. Refer to Class 7 Science solutions and previous years' CBSE board toppers' answer scripts (available on CBSE official website) to understand answer presentation techniques.

Q32. Describe the structure and function of the human heart with a labelled diagram.
Q33. Explain how water and minerals are transported in plants. What role does transpiration play?
Q34. Compare the transport system in animals and plants in a tabular form (any five points).
Q35. (HOTS) A potted plant is covered with a transparent polythene bag and kept in sunlight. After a few hours, water droplets appear inside the bag. Explain why.

Case Study Question

Case-based questions are now a regular feature in CBSE exams, including Class 7 internal assessments. They test your ability to apply chapter concepts to real or hypothetical situations. Read the passage carefully, underline key facts, and then answer the sub-questions. Each case study typically has 3-4 parts worth 1 mark each. These questions develop analytical thinking and connect textbook knowledge to everyday observations, an important skill for higher classes and competitive exams. CBSE introduced case studies to move away from rote learning. In 2024, many schools included at least one case-study question in Class 7 Science term papers. Answer in brief, precise sentences. Avoid lengthy explanations unless asked. Use data or numbers from the passage wherever applicable. This section simulates how science works in the real world, where you interpret observations and draw conclusions based on established principles from NCERT Class 7 Science Chapter 7.

Complete Answer Key with Explanations

Use this answer key to check your responses after completing the entire worksheet. Award yourself marks honestly and identify weak areas for revision. For MCQs, simply tally correct answers. For descriptive answers, compare your response with the model answer: award full marks if all key points are present, partial marks if you missed one or two points. Understanding why an answer is correct (or why you got it wrong) is more valuable than the marks themselves. Go back to your NCERT Class 7 Science textbook and read the relevant section again if you scored poorly in any area. Self-assessment builds exam temperament and helps you track progress over weeks. Many CBSE toppers maintain error logs, noting down every mistake and revising those specific points before exams. After reviewing the answers, re-attempt incorrect questions after two days to reinforce learning. This spaced repetition technique significantly improves long-term retention and exam performance.

How should I use the answer key provided in this worksheet?+

Attempt all questions first without referring to the answer key. After completion, check each answer, award yourself marks, identify weak areas, and revise those topics from your NCERT textbook before re-attempting incorrect questions.

Are diagrams important for Chapter 7 Transportation in Animals and Plants in CBSE exams?+

Yes, diagrams of the human heart, excretory system, and xylem-phloem cross-section are commonly asked and can earn you 1-2 bonus marks if labelled neatly and accurately. Practice drawing them freehand regularly.

What are xylem and phloem, and how are they different?+

Xylem is made of dead tubular cells and transports water and minerals upward from roots to leaves. Phloem consists of living cells and transports food (sugars) from leaves to all plant parts in both directions.

How many marks does Chapter 7 usually carry in CBSE Class 7 Science exams?+

Chapter 7 typically carries 8-10 marks in term exams, distributed across 2-3 MCQs, 1-2 short-answer questions, and 1 long-answer question, sometimes with a diagram or case-study component.

What is the role of the kidneys in the human excretory system?+

Kidneys filter blood to remove metabolic waste like urea, excess salts, and water. The filtered waste forms urine, which travels via ureters to the urinary bladder for storage and is expelled through the urethra.

Why does the left ventricle have a thicker wall than the right ventricle?+

The left ventricle pumps oxygenated blood to the entire body, requiring more force, so its muscular wall is thicker. The right ventricle only pumps blood to the nearby lungs, needing less pressure and hence thinner walls.

What is transpiration and why is it important for plants?+

Transpiration is the loss of water vapour from plant leaves through stomata. It creates a suction pull that helps water and minerals move upward, cools the plant, and maintains turgidity for structural support.

Can I use this worksheet for group study or classroom tests?+

Absolutely. Teachers can use this worksheet for classroom quizzes, homework, or internal assessments. Students can solve it in study groups, discuss answers, and learn collaboratively, which often improves understanding and retention.
