Example cell biology quiz questions

Which organelle produces most of a cell's ATP?Mitochondria. Their inner membrane hosts the electron transport chain, which drives most ATP synthesis.

True or false: animal cells have a cell wall made mainly of cellulose.False. Only plant cells have a cellulose cell wall; animal cells are bounded by the plasma membrane alone.

Why can't glucose diffuse freely across the plasma membrane?Glucose is large and polar, and the hydrophobic core of the phospholipid bilayer blocks it, so carrier proteins move it across.

What is osmosis?Osmosis is the movement of water across a selectively permeable membrane, from lower to higher solute concentration.

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

Quizzes from your own material

Upload PDFs, DOCX and PPTX files, plain text notes or photos of pages, and get questions written from that content.

Three question formats

Multiple choice, true/false and short answer questions, each with an explanation of the correct answer.

Study in the browser

The free plan lets you take quizzes in the browser. Plus adds PDF, DOCX, Anki and CSV export.

How it works

Upload your notes

Add a PDF, slides, a DOCX file or a photo of a page.

Pick the question types

Choose multiple choice, true/false or short answer for your set.

Study and review

Take the quiz, then read the explanation for every answer you missed.

A practical way to use the free plan is to save generations for the material you will actually be tested on. Turn a lecture deck or a unit summary into one quiz, take it, and then decide whether the explanations were useful enough to justify more generations.

Explanations matter as much as the questions. When you miss an item, the reason it was wrong is the part that sticks, so review those explanations before you retake the quiz.

Frequently asked questions

How many practice questions should a quiz cover for cell biology?

A set of 10 to 20 questions on one topic is a manageable sitting. Retake the same set after a day to see what you still remember.

Why do quizzes work better than rereading notes?

Answering a question forces recall, which is harder than recognizing a highlighted sentence. Reading the explanation for each wrong answer shows exactly where your understanding has gaps.

Is the free plan really unlimited?

No. The free plan includes 3 generations per month and browser study only. Unlimited generations are part of Plus, which costs $39 a year or $7.99 a month.

Can I export my quizzes?

Exports are paid features. Plus includes PDF, DOCX, Anki and CSV export, and Pro adds QTI 2.1 and Moodle XML for learning management systems.
