Living things & life processes
Take your time. Show your thinking.
1. What is the basic building block (smallest living unit) of all plants and animals: the cell or the grain of sand?
Sun + H₂O → Growth & Life
2. Which microscopic living organisms can only be seen with a microscope (such as bacteria in yoghurt): microorganisms (microbes) or pebbles?
Sun + H₂O → Growth & Life
3. Which of these is a living organism: a coral polyp or a glass marble?
Sun + H₂O → Growth & Life
4. Is a steel spoon made from iron ore something that was “never alive” or “currently alive”?
Sun + H₂O → Growth & Life
5. When a sunflower turns its stem toward the light, which life process is it showing: sensitivity (responding to changes) or rusting?
Sun + H₂O → Growth & Life
6. When a caterpillar turns into a pupa (chrysalis) and emerges as a butterfly, what is this life-cycle change called: metamorphosis or hibernation?
Sun + H₂O → Growth & Life
7. Do all living things need food (nutrition) and water to stay alive (Yes / No)?
Sun + H₂O → Growth & Life
8. How do green plants obtain their food differently from animals: plants make food using sunlight, whereas animals eat plants or other animals, or plants eat rocks?
Sun + H₂O → Growth & Life
9. What do we call the removal of metabolic waste products (such as carbon dioxide and urea) from a living body: excretion or reflection?
Sun + H₂O → Growth & Life
10. What is the correct order of a flowering plant’s life cycle: Seed → Seedling → Mature plant with flowers → Fruit with seeds, or Fruit → Seed → Leaf?
Sun + H₂O → Growth & Life
11. Which part of a plant cell gives it a rigid box-like shape and is not found in animal cells: the cell wall or the heart?
Sun + H₂O → Growth & Life
12. What is the correct order of a frog’s life cycle: Egg (spawn) → Tadpole → Froglet → Adult frog, or Adult frog → Egg → Tadpole?
Sun + H₂O → Growth & Life

Living things & life processes
Answers and reasoning. Review before teaching.
1. What is the basic building block (smallest living unit) of all plants and animals: the cell or the grain of sand?
The cell
All living organisms are composed of one or more cells.
2. Which microscopic living organisms can only be seen with a microscope (such as bacteria in yoghurt): microorganisms (microbes) or pebbles?
Microorganisms (microbes)
Microorganisms are tiny living things invisible to the naked eye.
3. Which of these is a living organism: a coral polyp or a glass marble?
Coral polyp
Coral polyps are living marine animals.
4. Is a steel spoon made from iron ore something that was “never alive” or “currently alive”?
Never alive
Metal refined from mineral rock was never a living organism.
5. When a sunflower turns its stem toward the light, which life process is it showing: sensitivity (responding to changes) or rusting?
Sensitivity (responding to changes)
Living things sense and respond to stimuli such as light, touch and gravity.
6. When a caterpillar turns into a pupa (chrysalis) and emerges as a butterfly, what is this life-cycle change called: metamorphosis or hibernation?
Metamorphosis
Metamorphosis is the biological transformation from larva to adult.
7. Do all living things need food (nutrition) and water to stay alive (Yes / No)?
Yes
All living organisms require energy and nutrients to maintain life processes.
8. How do green plants obtain their food differently from animals: plants make food using sunlight, whereas animals eat plants or other animals, or plants eat rocks?
Plants make food using sunlight, whereas animals eat plants or other animals
Plants are autotrophs (producers); animals are heterotrophs (consumers).
9. What do we call the removal of metabolic waste products (such as carbon dioxide and urea) from a living body: excretion or reflection?
Excretion
Excretion removes waste substances produced by metabolism.
10. What is the correct order of a flowering plant’s life cycle: Seed → Seedling → Mature plant with flowers → Fruit with seeds, or Fruit → Seed → Leaf?
Seed → Seedling → Mature plant with flowers → Fruit with seeds
A germinating seed grows into a seedling, matures, flowers and produces new seeds.
11. Which part of a plant cell gives it a rigid box-like shape and is not found in animal cells: the cell wall or the heart?
Cell wall
Plant cells have a cellulose cell wall outside the cell membrane.
12. What is the correct order of a frog’s life cycle: Egg (spawn) → Tadpole → Froglet → Adult frog, or Adult frog → Egg → Tadpole?
Egg (spawn) → Tadpole → Froglet → Adult frog
Frogs hatch from spawn as aquatic tadpoles before developing legs and lungs.
