What this practice covers
These questions are drawn from past CIE 0654 Co-ordinated Sciences papers and filtered to reproduction. You answer, you find out immediately whether you were right, and you get the reasoning for the correct option and for each distractor. Wrong answers go to a mistakes locker so you can come back to exactly those.
Practice is free. You need an account only so your progress and your mistakes are still there next time.

What examiners see students get wrong here
These are the errors that cost marks on reproduction, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Using pollination and fertilisation as though they meant the same thing.
- Saying the ovary becomes the seed. The ovule becomes the seed; the ovary becomes the fruit.
- Saying germinating seeds need light.
- Saying fertilisation happens in the uterus. It happens in the oviduct.
- Saying the mother's and fetus's blood mix in the placenta.
- Swapping oestrogen and progesterone.
- Saying asexual offspring show variation.
Revise it first
