Example biology quiz questions

What organelle is the main site of aerobic respiration in eukaryotic cells?The mitochondrion. It houses the Krebs cycle and the electron transport chain, which produce most of the cell's ATP.

True or false: DNA replication is semiconservative.True. Each new double helix keeps one original strand and one newly synthesized strand, as shown by the Meselson-Stahl experiment.

Which phase of mitosis is when sister chromatids separate?Anaphase. Spindle fibers pull the sister chromatids toward opposite poles of the cell.

What is the role of RNA polymerase?It synthesizes an RNA copy of a gene during transcription, so the cell can make the proteins that gene encodes.

Which blood type is the universal donor for red blood cells?Type O negative. Its red cells lack A, B and Rh D antigens, so recipients are less likely to react.

Pick multiple-choice, true/false or open questions for the quiz.

Take the quiz

Answer in the browser and read the explanation after each question.

Ready-made trivia quizzes are fun for warm-ups, but they rarely match a chapter on cell respiration or a unit on genetics. DeckOwl reads your material and writes questions from it, with an explanation attached to each answer.

Start on the free plan with 3 generations a month and study in the browser. Plus adds unlimited generations and exports, and students get 40% off with a school email. No credit card is needed to start.

Frequently asked questions

How many questions should a biology quiz have?

Ten to twenty questions per chapter is a practical range for a single sitting. Shorter quizzes work better for daily review, and longer ones suit a full unit before an exam.

How can I study biology quizzes effectively?

Answer each question before reading the explanation, and redo the ones you missed after a day or two. Explaining the right answer out loud helps it stick.

Can I use this for Jetpunk-style quizzes?

DeckOwl builds quizzes from your own material rather than a public trivia library, so the questions match your course. Upload your notes and it writes multiple-choice, true/false or open questions from them.

Do I need to pay to export my quiz?

Yes. The free plan lets you study in the browser, while Plus adds PDF, DOCX, Anki and CSV export and Pro adds QTI 2.1 and Moodle XML.
