Section A: Core Concepts

Question 1mcq

B.Making leaves green

C.Producing urine in the bladder

D.Transporting dissolved substances through blood

Question 2mcq

A student says platelets carry oxygen because they are in blood. What is the correction?

A.Red blood cells carry oxygen; platelets help clotting.

B.Platelets digest food in the stomach.

C.White blood cells carry all oxygen.

D.Plasma is a type of bone.

Question 3mcq

If a person has very low white blood cell count, which function may be most affected?

A.Carrying xylem sap

B.Fighting infections

C.Making soil humus

D.Opening stomata

Question 4mcq

A diagram shows blood moving from heart to a leg muscle, then through tiny vessels, then back to heart. Which tiny vessels allow exchange in the muscle?

A.Ureters

B.Capillaries

C.Bronchi

D.Xylem tubes

Question 5mcq

Which statement is generally correct about veins?

A.They always carry blood away from the heart.

B.They are the tubes that carry urine from kidneys.

C.They carry blood toward the heart.

D.They make food in plants.

Question 6mcq

A student says arteries and veins are the same because both carry blood. What is the best correction?

A.Arteries carry urine and veins carry air.

B.Only veins are connected to the heart.

C.Arteries exist only in plants.

D.They both carry blood, but arteries carry it away from the heart and veins carry it toward the heart.

Section B: Observations and Data

Question 7mcq

A student measures pulse for

15

seconds and counts

20

beats. What is the pulse rate per minute?

20

beats per minute

35

beats per minute

80

beats per minute

300

beats per minute

Question 8mcq

Why is the wrist commonly used to feel pulse?

A.A vein there makes food.

B.The wrist contains stomata.

C.Urine passes through the wrist.

D.An artery lies close enough to the surface to feel its expansion.

Question 9mcq

A student compares pulse before and after exercise but counts for

10

seconds before and

30

seconds after. What is wrong?

A.The counting time is not the same, so comparison is unfair unless converted properly.

B.Pulse cannot be measured at all.

C.Exercise never affects pulse.

D.Only plants have pulse.

Question 10mcq

Which part stores urine temporarily before it leaves the body?

A.Urinary bladder

B.Kidney

C.Ureter only

D.Capillary

Question 11mcq

A student says the bladder filters blood. What is the correction?

A.The bladder pumps blood.

B.Kidneys filter blood; the bladder stores urine.

C.Ureters produce oxygen.

D.Kidneys store urine only and do not filter.

Question 12mcq

Which pair correctly matches organ and function in the urinary system?

A.Kidney: stores urine only

B.Bladder: filters blood

C.Ureter: carries urine from kidney to bladder

D.Urethra: carries blood to heart

Section C: Applications

Question 13mcq

Why do roots need root hairs?

A.They increase surface area for absorbing water and minerals.

B.They make flowers colourful.

C.They carry oxygen in blood.

D.They store urine.

Question 14mcq

If xylem tubes are blocked in a stem, what is most likely to happen first?

A.The plant will pump blood faster.

B.Leaves may wilt because less water reaches them.

C.The roots will start breathing through gills.

D.The phloem will become a kidney.

Question 15mcq

A student labels xylem as the tube carrying food from leaves. What should be corrected?

A.Xylem carries urine in animals.

B.Phloem carries only oxygen in blood.

C.Xylem carries water and minerals; phloem carries food.

D.Plants have no transport tissues.

Question 16mcq

A ring of bark is removed from a woody stem and food movement is affected. Which tissue is likely damaged?

A.Xylem only in the centre

B.Phloem

C.Kidney

D.Alveoli

Question 17mcq

Which pairing is correct?

A.Xylem: urine; phloem: blood

B.Xylem: oxygen in humans; phloem: pulse

C.Xylem: water and minerals; phloem: food

D.Xylem: storms; phloem: soil profile

Question 18mcq

A student says phloem is needed only at night because food is made during daytime. What is the best response?

A.Phloem works only in animals.

B.Food never moves from leaves.

C.Roots make all their food using sunlight.

D.Food transport can continue to parts that need or store food, not only at night.

Section D: Reasoning Challenge

Question 19mcq

On a hot windy day, what is likely to happen to transpiration rate?

A.It always becomes zero.

B.It changes into digestion.

C.It stops xylem from existing.

D.It usually increases.

Question 20mcq

A student says transpiration is always harmful because plants lose water. What is the best correction?

A.It can cause water loss, but it also helps water movement and cooling.

B.It never involves water.

C.It happens only in animals.

D.It is the same as heartbeat.

Question 21mcq

A.Oxygen cannot enter leaves.

B.Xylem stops carrying water in plants.

C.Urine cannot be stored in the bladder.

A.Phloem is damaged.

B.Kidneys are damaged.

C.Gills are blocked.

D.Arteries in the stem are missing.
