What this practice covers
These questions are drawn from past CIE 0654 Co-ordinated Sciences papers and filtered to organisation of the organism. 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 organisation of the organism, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Saying plant cells have a cell wall instead of a cell membrane.
- Saying the nucleus is the structure found only in plant cells. That line separates bacteria from plants and animals, not plants from animals.
- Forgetting the words "large" and "permanent" in front of vacuole.
- Giving root hair cells chloroplasts, or red blood cells a cell wall.
- Saying the nucleus carries out photosynthesis because it controls the cell. Controlling a process is not the same as being the site of it.
- Writing the magnification formula upside down as actual size divided by image size, which gives an answer below 1 for anything magnified.
- Dividing a measurement in millimetres by one in micrometres without converting.
- Calling a group of different tissues a tissue rather than an organ.
Revise it first
