Example cell biology quiz questions (common study topic)

Which organelle produces most of a cell's ATP?Mitochondria. They carry out cellular respiration, which converts glucose and oxygen into ATP.

True or false: plant cells have a cell wall made mainly of cellulose.True. Cellulose gives plant cell walls their rigidity, while animal cells have no cell wall.

What is the main function of ribosomes?Protein synthesis. Ribosomes read mRNA and link amino acids into polypeptide chains.

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

Which molecules cross a phospholipid bilayer most easily?Small nonpolar molecules such as oxygen and carbon dioxide. Their lack of charge lets them pass through the hydrophobic core without help.

Generate the full set

Built from your material

Quizzes come from your own PDFs, DOCX files, slides, text or photos of pages, so the questions match what your class actually covers.

Explanations for every answer

Each multiple-choice, true/false and short-answer question includes an explanation, so wrong answers become quick lessons.

Study in the browser

Take quizzes on any device with a browser. The free plan has no install step and no exports.

How it works

Upload your notes

Add a PDF, slide deck, Word file, plain text or a photo of a page. Images are read with text recognition.

Choose a question type

Pick multiple choice, true/false or open questions, then generate the quiz.

Play and review

Work through the quiz, read the explanations for misses, and repeat until the answers come easily.

Ready-made printable quizzes and public quiz libraries are fine for warm-ups, but they cannot reflect your syllabus. DeckOwl reads the file you upload and writes questions from it, so the practice stays tied to your course.

Free accounts get 3 generations a month and can study in the browser. Paid plans add unlimited generations and exports for PDF, DOCX and Anki, and Pro adds QTI 2.1 and Moodle XML for teachers who load quizzes into a learning system.

Frequently asked questions

How do I make a good practice quiz for a biology exam?

Start with the chapter headings and key terms, then write questions that ask you to apply them, such as predicting what happens when a structure is removed. Review explanations for every miss and retake the quiz after a day or two.

How many questions should a study quiz have?

Ten to twenty questions per session works well for most students, because short sets are easier to finish and review. Use a second set on the same material later to check what you retained.

Can I quiz myself on my own notes for free?

Yes. The free plan includes 3 generations a month and lets you study the quiz in your browser. Exports and unlimited generations require a paid plan.

Can I export a quiz to Moodle or PDF?

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