Example biology quiz questions (a common study topic)

Which organelle produces most of a cell's ATP?The mitochondrion, because it carries out most of the reactions that make ATP.

True or false: plant and animal cells both have a cell wall.False, because only plant cells have a cell wall, so animal cells lack one.

Which molecule carries amino acids to the ribosome during translation?Transfer RNA (tRNA), because its anticodon pairs with the mRNA codon.

What is the main job of the Golgi apparatus?It modifies, sorts and packages proteins and lipids into vesicles for delivery elsewhere in the cell.

Why does a cell swell when placed in pure water?Water moves in by osmosis because the cytoplasm has more dissolved solute than the pure water outside.

How it works

Upload your material

Add a PDF, slide deck, DOCX file, notes or a photo of a page.

Choose a question type

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

Study and retake

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

Quizzes help most when you answer before checking. Write your answer, read the explanation, then note why your wrong choices were wrong. Questions you miss can be retaken after a day or two, which is the point where recall starts to stick.

Exports to PDF, DOCX, Anki and CSV are part of the paid Plus plan, and QTI 2.1 and Moodle XML export are in Pro. The free plan is for studying in the browser.

How many quiz questions should I make for biology exam prep?

What is the best way to study from quiz explanations?

Answer each question before reading the explanation, then write down why each wrong choice fails. Retake the missed questions after a day or two.

Is there a free quiz app I can download?

DeckOwl runs in your browser, and the free plan includes 3 generations per month with studying in the browser. Exporting to PDF or DOCX requires the Plus plan, which costs $99.90 a year or $9.99 a month.
