Why generate your own biology quiz competition questions

Running a biology quiz competition works best when the questions match what your class actually covered, and ready-made question sets often miss that. DeckOwl builds questions from your own material, so a teacher or student can start from the chapter being studied.

Write questions straight from your own chapter or slides
Mix multiple-choice, true/false and short-answer for variety
Read the explanation for every answer before the round
Check accuracy on diagrams, numbers and terminology

Example biology questions for competition practice

Which organelle produces most of a eukaryotic cell's ATP?Mitochondria. They carry out oxidative phosphorylation, the main ATP-producing step of aerobic respiration.

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.

Which phase of mitosis pulls sister chromatids to opposite poles?Anaphase. Spindle fibers shorten and pull the sister chromatids apart toward opposite ends of the cell.

What does Hardy-Weinberg equilibrium assume about population size?A large population. Small populations are more strongly affected by genetic drift, which can change allele frequencies by chance.

Which enzyme unwinds the DNA double helix during replication?Helicase. It breaks the hydrogen bonds between base pairs so the two strands can separate.

Questions from your own material

Generate questions from the chapter, slides or notes your class actually covered, not a generic question bank.

Explanations for every answer

Each multiple-choice, true/false and short-answer question includes an explanation, so the round doubles as review.

Study in the browser

Practice the round in your browser on the free plan, and export to PDF or DOCX on Plus.

How it works

Upload your biology material

Add a PDF, DOCX, PPTX, plain text file or a photo of a page.

Choose question types

Pick multiple-choice, true/false or short-answer questions for the round.

Review and run the round

Check the questions for accuracy, fix anything the AI misread, then use the set for your competition.

Upload a PDF, DOCX, PPTX, plain text or a photo of a page, and the tool produces multiple-choice, true/false or short-answer questions, each with an explanation. Check the set before the round, since the AI can misread a diagram or get a detail wrong.

Free accounts get 3 generations a month and can study in the browser. Plus adds unlimited generations and PDF or DOCX export, while Pro adds QTI 2.1 and Moodle XML export for learning systems.

Frequently asked questions

How many questions should a biology quiz competition round have?

Most rounds work well with 10 to 20 questions, mixing easy recall with a few harder application items. Varying the question types tests both fast recall and reasoning.

Which biology topics suit a quiz competition?

Topics with clear, checkable facts work best, such as cell organelles, DNA replication, mitosis stages and enzyme function. Avoid questions that depend on the exact wording of one lecture.

Can I export my competition quiz?

Exporting to PDF and DOCX is part of the Plus plan, and QTI 2.1 and Moodle XML export are on Pro. The free plan lets you study in the browser but does not include exports.

Is there a free plan to try it first?

Yes, the free plan includes 3 generations per month and no credit card is needed to start. Students can get 40% off Plus with a school email.
