Context
Explore a collection of 200 biology trivia questions and answers covering the human body, animals, plants, cells, genetics, and more.
On this page
A good biology trivia night needs questions people can answer out loud, plus answers you can check without arguing. This list gives you 200 biology trivia questions and answers across the human body, animals, plants, cells, genetics, and ecology. Use them for a classroom warm-up, a science club round, or a quiz you send as a form.
Later in this article you will also see how to turn a short set into a shareable Formms quiz, with a live walkthrough.
How to use these biology trivia questions
Pick one topic round, or mix easy and medium questions from several sections.
Pick a section that matches your audience. Human body and animals work for mixed ages. Cells and genetics suit a biology class that already knows the vocabulary.
For a live quiz, ask the question, wait for answers, then read the answer line. For a digital round, put five to ten items into a form with multiple choice options and score from the responses later.

How to create a biology trivia quiz with Formms
Describe the quiz, review the draft questions, then share a link or QR code.
You do not need to paste all 200 questions into one form. A strong trivia form is short: a name field, five to eight multiple choice items, and a clear submit button. Formms can draft that from a plain-language prompt, then you edit anything that looks wrong.
Start from the free template
Open the biology trivia quiz template. It already has seven classic questions with one correct option each. Duplicate the idea, swap in questions from this article, and publish.
The template page shows a live preview you can try before you copy it into your account.
Or describe the quiz to AI
In the Formms dashboard, start a new form and describe what you want. Say who will play, how many questions, and that answers should be multiple choice.
Start a new form from the dashboard when you want a fresh quiz.
A clear prompt names the topic, the number of questions, and the format.
Review every option. Trivia only works when one answer is clearly right.
Share the quiz
Publish, then copy the short link or download a QR code. Players open it on a phone. You get a notification when someone finishes, and you can export CSV if you want to score teams.
Send the short link in chat, or put the QR on a slide.
A QR code works well for classroom screens and pub quiz sheets.
Players pick one option per question and submit when they are done.

Tips for hosting biology trivia
Short rounds, one clear answer, and a mix of easy and medium questions.
- One correct answer. If a question has two fair answers, rewrite it.
- Say the source of truth out loud. For school use, stick to what your textbook already taught.
- Mix topics. A genetics question after an animal question resets attention.
- Score lightly. A Formms response list is enough for most nights. You do not need a fancy leaderboard to start.
- End with something everyone knows. Leave people laughing, not stuck on codon tables.
FAQ
How many biology trivia questions should I use in one quiz?
Five to ten is enough for a form people finish. Use this bank of 200 when you want fresh rounds over a term, not one giant form.
Can I use these questions in a classroom?
Yes, for informal review and game nights. They are general knowledge items, not a substitute for your curriculum or exam board wording.
How do I turn these into a multiple choice form?
Pick a question, write the correct answer plus three plausible wrong options, and use a single-choice field. The biology trivia quiz template shows the shape.
Does Formms grade the quiz automatically?
Formms collects answers. You compare them to the answer key (this article or your own). Export CSV when you want to score offline.
Where can I find more form ideas for school?
Browse student interest surveys and other education templates on the templates hub, or read how to create a free form with unlimited responses.
Conclusion
You now have 200 biology questions to pull from, along with a simple way to turn a handful into a short digital quiz. Choose five to ten that fit your group, check the wording against what they have learned, and save the rest for another round. When you are ready, build the first quiz using Formms, share the link, and let the responses guide what you ask next.
