Biology flashcards and quizzes

Biology flashcards work best for the subject's large vocabulary and its step-by-step processes, while practice quizzes check you can apply them to unfamiliar examples, which is what most exam questions ask you to do.

Core biology topics

Pick a topic to open a ready-made set request: choose your level and counts, then generate. For exam revision, narrow it to your unit or paste your class notes.

Levels

What does biology cover at each level?

School (about ages 11–16)

Cells and organisation, the human body, plants, inheritance, evolution and ecosystems, with required practical work.

Pre-university (A-Level, IB, AP)

The same themes in molecular depth: biochemistry, gene expression, physiology, populations and statistics in experiments.

University

Specialised modules such as molecular biology, genetics, physiology, ecology and microbiology, often with heavy terminology.

Courses differ by country and exam board, so check your own specification. Our exam board guides cover 23 countries and curricula.

Exam boards

Exam board guides for biology

Biology is examined by 38 of the boards and qualifications we cover. Each guide explains grading, exam dates and what to know, with sets matched to that board.

Revision

How should you revise biology?

Learn processes as sequences

For processes like protein synthesis or the cardiac cycle, make cards that ask what happens next. Exams often ask you to describe steps in order.

Use the exact term

Mark schemes reward precise words: diffusion, osmosis and active transport are not interchangeable. Put the definition on the back of the card word for word.

Practise cause and effect

"Explain" questions want a chain: this happens, so that happens, which means this. Quiz explanations show you what a full chain looks like.

Don't skip the practicals

Required practicals and data questions carry real marks. Make cards on methods, variables and what results show.

Watch out

What are the most common biology mistakes?

  • Mistake: Plants only respire at night.

    Correct: Plants respire all the time. In daylight photosynthesis usually happens faster than respiration, so there is a net uptake of carbon dioxide.

  • Mistake: Mitosis makes sperm and egg cells.

    Correct: In humans, gametes are made by meiosis, which halves the chromosome number. Mitosis makes genetically identical body cells for growth and repair.

  • Mistake: Animals adapt during their lifetime, and that is evolution.

    Correct: Evolution is a change in a population over many generations: individuals with useful inherited variations survive and reproduce more, passing them on.

  • Mistake: Arteries carry oxygenated blood.

    Correct: Arteries carry blood away from the heart. The pulmonary artery carries deoxygenated blood to the lungs.

Examples

Sample biology flashcards

One idea per card, a clear question, a short answer. This is the style every generated set follows.

Biology

What is diffusion?

Back

The net movement of particles from an area of higher concentration to an area of lower concentration.

Biology

What is the function of a ribosome?

Back

To make proteins, by joining amino acids in the order coded for by messenger RNA.

Biology

How many chromosomes are in a normal human body cell?

Back

46, in 23 pairs. Human sperm and egg cells have 23.

FAQ

Biology: questions

What are the most important biology topics to revise?

It depends on your specification, but almost every course covers cells, organisation and the human body, inheritance and genetics, evolution, and ecology. Use your specification as a checklist and make a set for each section.

How do I memorise biology definitions?

Make one flashcard per definition with the exact wording your course uses, say the answer out loud before you flip, and come back to the cards over several days rather than cramming.

Are flashcards enough to revise biology?

They cover the knowledge, but exams also test application and data analysis. Pair flashcards with quiz questions and past-paper questions that use unfamiliar examples.
