Short Answer Questions (2–3 marks)

Q6. Differentiate between a tendon and a ligament, and state the tissue type both belong to.
Ans: A tendon connects muscle to bone, while a ligament connects bone to bone. Both are made of connective tissue.

Q7. Explain why a hinge joint (like the elbow) cannot rotate in all directions the way a ball-and-socket joint (like the shoulder) can.
Ans: A hinge joint’s structure only allows back-and-forth movement in a single plane, like a door hinge, while a ball-and-socket joint has a rounded end fitting into a cup-shaped socket, allowing movement in multiple directions and planes.

Q8. Why is a balanced diet with adequate protein, calcium, and vitamin D important for the musculoskeletal system?
Ans: Protein supports muscle repair and growth, calcium is essential for bone strength and density, and vitamin D helps the body absorb calcium effectively — together these keep bones and muscles strong and reduce the risk of weakness or damage.

Q9. A gardener notices that cutting off the tip of a plant’s main shoot causes the plant to stop growing taller but start growing bushier from the sides. Explain this observation using the concept of meristematic tissue.
Ans: The shoot tip contains the apical meristem, the meristematic tissue responsible for the plant’s upward growth. Removing it stops further upward growth from that point, but it activates other meristematic regions (lateral/axillary buds) along the sides of the stem, causing the plant to branch out and grow bushier instead.

Q10. An athlete sprains their ankle during a match, damaging the tissue that connects two of the ankle bones together. Identify the tissue type and structure most likely injured, and explain its function.
Ans: The injured structure is most likely a ligament, made of connective tissue, which connects bone to bone. Its function is to stabilise and hold joints together while allowing appropriate movement; a sprain occurs when a ligament is stretched or torn beyond its normal range.
