Example cell biology quiz questions

Which organelle produces most of a cell's ATP through aerobic respiration?The mitochondrion. The citric acid cycle and oxidative phosphorylation, which take place there, yield most of the cell's ATP.

True or false: Plant cell walls are made mainly of cellulose.True. Cellulose gives plant cell walls their rigidity, and animal cells do not have a cell wall.

What is the main function of the rough endoplasmic reticulum?Synthesizing proteins for secretion or for membranes, because ribosomes on its surface build them.

In which phase of mitosis do sister chromatids separate?Anaphase. Spindle fibers pull the sister chromatids toward opposite poles of the cell.

Why does a cell shrink when placed in a concentrated salt solution?The solution is hypertonic, so water leaves the cell by osmosis to dilute the outside solution.

Multiple choice, true/false and short answer

Mix question types in one set. Each question includes an explanation, so a wrong answer teaches you why.

The free plan lets you study in the browser. Paid plans export to PDF, DOCX and Anki, and Pro adds QTI 2.1 and Moodle XML.

How it works

Upload your PDF

Add the file or a photo of the page. No credit card is needed to start.

Choose question types

Pick multiple choice, true/false or short answer, or combine them in one quiz.

Quiz yourself and review

Answer the questions, read each explanation, and retake the ones you missed.

DeckOwl reads the text of your PDF, picks out key terms and processes, and writes questions that stay close to what the document says. Each question can be multiple choice, true/false or open, and each comes with an explanation of the correct answer.

Scanned pages work too, since photos are read with text recognition. Review the questions before you study, because no generator phrases every point perfectly, and keep the ones that test ideas you really need to know.

Frequently asked questions

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

Aim for about one question per key term or process in each section, and remove any that repeat the same idea. Shorter, focused sets are easier to review than long ones.

What is the best way to study quiz questions from a textbook chapter?

Answer each question without looking at the source, then read the explanation for every miss. Retake the questions you missed after a day or two so the review sticks.

Can I export my quiz from the free plan?

No. The free plan includes 3 generations per month and studying in the browser, and exports require a paid plan.

Which formats can I export to?

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