Biology quizzes from the material you already have

A ready-made biology quiz rarely matches what your instructor covered this week, so the most useful practice comes from your own lecture notes, slides and readings. DeckOwl reads those files and writes questions about the terms, processes and diagrams in them.

  • Questions drawn from your own notes, slides and PDFs
  • Multiple choice, true/false and short answer formats
  • Explanations that show why each answer is right or wrong
  • Free plan to study in the browser, with exports on paid plans
Example biology quiz questions with answers
Which organelle is the main site of aerobic respiration in eukaryotic cells?Mitochondria. They contain the enzymes of the Krebs cycle and electron transport chain that 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 and Stahl experiment.
What is the role of RNA polymerase during transcription?It synthesizes an RNA strand complementary to the DNA template, building the RNA 5' to 3' as it reads the template 3' to 5'.
Which phase of mitosis is when sister chromatids separate?Anaphase. After the centromeres split, spindle fibers pull the sister chromatids toward opposite poles of the cell.
Why does the sodium-potassium pump need ATP?It moves 3 sodium ions out and 2 potassium ions in against their concentration gradients, which requires energy from ATP hydrolysis.

Multiple choice, true/false and short answer

Mix question types for each chapter so you practice recognizing terms, judging statements and explaining processes in your own words.

Explanations for every answer

Each question includes a short explanation, so a wrong answer shows you the reasoning behind the right one.

Built from your material

Works from PDF, DOCX, PPTX, plain text notes and photos of pages, so the questions match your course instead of a generic textbook.

How it works

Upload your biology material

Add a PDF, slide deck, Word file, pasted notes or a photo of a page. Photos are read with text recognition.

Choose the question types

Pick multiple choice, true/false, short answer or a mix, then generate the quiz.

Quiz yourself and review

Answer in the browser, read the explanations and retake the questions you missed.

If you were hoping for a printable, ready-made quiz, the closer match is one you generate from your own course material. That keeps the questions aligned with your syllabus, and the explanations point you back to the exact section you need to review.

Biology topics with clear cause and effect, such as cellular respiration, DNA replication and membrane transport, suit multiple-choice and true/false questions well. Process topics also benefit from short-answer questions that ask you to explain each step in order.

Frequently asked questions

How many questions should a biology quiz have for one chapter?

Aim for enough questions to cover each main term and process in the chapter, then add more for the sections your instructor stressed. Repeating the missed questions is usually more useful than adding new ones.

Which biology topics work best for practice quizzes?

Topics with clear cause and effect, like mitosis, photosynthesis and the sodium-potassium pump, suit multiple-choice and true/false questions. Process topics also benefit from short-answer questions that ask you to explain each step.

Can I export the quiz to share with classmates or an LMS?

Exporting is a paid feature. The Plus plan includes PDF and DOCX export, and the Pro plan adds QTI 2.1 and Moodle XML for learning management systems.

Is there a free plan to try it first?

Yes. The free plan includes 3 generations per month and studying in the browser, and no credit card is needed to start. Exports require a paid plan.
