Question
What is a prokaryotic cell?
Answer
A cell whose DNA is not enclosed in a nucleus.
- Bacterial cells are prokaryotic
- They are much smaller than eukaryotic cells
Tutor tip
Prokaryotic does not mean "simple". The mark is for the DNA not being in a nucleus.

Who it is for
These flashcards are for Edexcel GCSE Biology students sitting the 1BI0 specification who want the exact mark-scheme wording for Topic 1, rather than vague definitions that drop marks. They suit students meeting cells, microscopy, enzymes and transport for the first time and those revising for the real thing. They are written for Edexcel, not adapted from another board.

Frequently asked questions
Is this deck for the Edexcel specification?
Yes. It is written specifically for Edexcel GCSE Biology (1BI0), Topic 1 Key Concepts in Biology, and follows the Edexcel section numbering from 1.1 to 1.17. It is not affiliated with Pearson Edexcel.
What does it cover?
Eukaryotic and prokaryotic cells, specialised cells, microscopy, size and scale, units and standard form, enzyme action, denaturation, changing enzyme activity, rate calculations, digestive enzymes, calorimetry, cell transport and percentage change. There are 74 cards across thirteen sections.
Does it include the core practicals?
No. The four core practicals in Topic 1, sections 1.6, 1.10, 1.13B and 1.16, are deliberately not covered in this deck. Everything else in the topic is.
Does it cover the Higher and Biology only content?
Yes. Section 1.14B calorimetry is Higher tier and Biology only, and it is included and labelled as such so you know whether you need it.
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 try it before I buy?
Yes. The first three cards are free to read on this page. Buy once to unlock all 74.
