1.1.1 Eukaryotes and prokaryotesDefinition
Question
Describe prokaryotic cells.
Answer
- Their genetic material is not enclosed in a nucleus. The DNA is free in the cytoplasm
- Bacterial cells are prokaryotic
- They are much smaller than eukaryotic cells
1.1.1 Eukaryotes and prokaryotesDefinition
Question
Describe the genetic material in a prokaryotic cell.
Answer
- A single loop of DNA, not enclosed in a nucleus
- May also contain one or more plasmids, which are small additional rings of DNA
Tutor tip
Plasmids are 'additional' rings. Saying a bacterium's DNA is only in plasmids loses the mark.

Frequently asked questions
Is this deck for the AQA specification?
Yes. It is written specifically for AQA GCSE Biology (8461) and the Biology content of Combined Science: Trilogy (8464), Topic 1 Cell Biology, with every card matched to the mark scheme. It is not affiliated with AQA.
What does it cover?
All of Topic 1: eukaryotes and prokaryotes, animal and plant cells, cell specialisation, differentiation, microscopy, culturing microorganisms, chromosomes, mitosis and the cell cycle, stem cells, and transport (diffusion, osmosis and active transport). There are 53 cards.
Do I get lifetime access?
Yes. It is a one-time payment, not a subscription. Once you buy the deck you keep access permanently on any device you sign in on.
Can I use it on my phone?
Yes. The viewer is built mobile-first, so you can flip, shuffle and filter cards on your phone, which is how most students revise.
Can I try it before I buy?
Yes. The first three cards are free to read on this page. Buy once to unlock all 53.
How is this different from a textbook?
Every bold word is an exact mark-scheme key word that earns a mark, and the examiner traps flag the mistakes that lose them. It is written to be revised, not read.
