Q1 · Difficulty 1/3

What is the function of the root system in plants?

  1. Photosynthesis
  2. Anchoring the plant and absorbing water and minerals from soil
  3. Producing flowers
  4. Releasing oxygen
Show answer & explanation
✓ Answer: B — Anchoring the plant and absorbing water and minerals from soil
Roots anchor plants in the soil and absorb water and dissolved minerals through root hair cells, which have a large surface area.
Q2 · Difficulty 1/3

A microorganism that causes disease is called a:

  1. nutrient
  2. pathogen
  3. vaccine
  4. hormone
Show answer & explanation
✓ Answer: B — pathogen
Pathogens cause disease.
Q3 · Difficulty 1/3

Which of the following is an example of an organ in the human body?

  1. Blood
  2. Muscle fibre
  3. Heart
  4. Circulatory system
Show answer & explanation
✓ Answer: C — Heart
Award 1 mark for recognising that the heart is an organ made of different tissues (muscle, nervous, connective) working together. A is incorrect because blood is a tissue. B is incorrect because a muscle fibre is a cell. D is incorrect because the circulatory system is a system, not an organ.
Q4 · Difficulty 1/3

What are the seven life processes (MRS GREN)?

  1. Movement, Reproduction, Sensitivity, Growth, Respiration, Excretion, Nutrition
  2. Memory, Running, Sleeping, Growing, Reading, Eating, Napping
  3. Making, Repairing, Sorting, Generating, Reducing, Expanding, Naming
  4. Moving, Recycling, Storing, Gaining, Resting, Eliminating, Nurturing
Show answer & explanation
✓ Answer: A — Movement, Reproduction, Sensitivity, Growth, Respiration, Excretion, Nutrition
MRS GREN: Movement, Reproduction, Sensitivity, Growth, Respiration, Excretion, Nutrition — the 7 characteristics of all living things.
Q5 · Difficulty 1/3

What is the water cycle?

  1. The process of cleaning water
  2. The continuous movement of water between the atmosphere, land, and oceans through evaporation, condensation, and precipitation
  3. Water flowing downhill
  4. The tides
Show answer & explanation
✓ Answer: B — The continuous movement of water between the atmosphere, land, and oceans through evaporation, condensation, and precipitation
The water cycle describes the continuous movement: evaporation → condensation → precipitation → collection. The sun drives this cycle.
Q6 · Difficulty 1/3

Which planet in the solar system is closest to the Sun?

  1. Venus
  2. Mercury
  3. Mars
  4. Earth
Show answer & explanation
✓ Answer: B — Mercury
Award 1 mark for correctly identifying Mercury as the innermost planet. A is incorrect — Venus is the second planet from the Sun. C is incorrect — Mars is the fourth planet. D is incorrect — Earth is the third planet from the Sun.
Q7 · Difficulty 1/3

The part of the cell that controls its activities is the:

  1. cytoplasm
  2. nucleus
  3. membrane
  4. vacuole
Show answer & explanation
✓ Answer: B — nucleus
The nucleus controls the cell.
Q8 · Difficulty 1/3

What is the correct order of levels of organisation in a living organism, from simplest to most complex?

  1. Cell → Tissue → Organ → System
  2. Tissue → Cell → System → Organ
  3. Organ → Tissue → Cell → System
  4. System → Organ → Tissue → Cell
Show answer & explanation
✓ Answer: A — Cell → Tissue → Organ → System
Award 1 mark for recognising that cells are the basic unit of life and combine to form tissues, which form organs, which form systems. B is incorrect because it places tissue before cell. C and D reverse the correct order.
