Primary 3 Science: Life Cycles Practice
Real Primary 3 Science questions on Life Cycles, pulled directly from the Olibits question bank — the same questions a child would actually see, not separately written for this page.

Real Life Cycles practice questions
Which of these animals goes through 'complete metamorphosis' (egg → larva → pupa → adult)?
Chicken
Cat
Butterfly ✓
Human
A butterfly's life cycle includes a larva (caterpillar) stage and a pupa (chrysalis) stage, which together make up complete metamorphosis.
Which of these life cycles includes a pupa stage?
Chicken
Dog
Cat
Mosquito ✓
A mosquito's life cycle is egg → larva → pupa → adult, which includes a pupa stage - unlike a chicken, dog or cat.
A cockroach's life cycle is egg → nymph → adult, with NO pupa stage. What is this pattern called?
Incomplete metamorphosis ✓
Complete metamorphosis
No metamorphosis
Budding
A life cycle with a nymph stage but no pupa stage is called incomplete metamorphosis.
How is a grasshopper's life cycle DIFFERENT from a butterfly's life cycle?
The grasshopper does not hatch from an egg.
The grasshopper has no pupa stage; its nymph already looks like a small adult. ✓
The grasshopper does not grow at all.
The grasshopper's life cycle has more stages than a butterfly's.
A grasshopper undergoes incomplete metamorphosis - its nymph looks like a small wingless adult - while a butterfly undergoes complete metamorphosis with a very different-looking larva and a pupa stage.
