Example intro biology quiz questions for students

Which organelle is the main site of ATP production in a eukaryotic cell?The mitochondrion. It carries out cellular respiration, which produces most of the cell's ATP.

True or false: prokaryotic cells have a membrane-bound nucleus.False. Prokaryotes lack a membrane-bound nucleus, so their DNA sits in a region called the nucleoid.

What does the enzyme helicase do during DNA replication?It unwinds the double helix by breaking hydrogen bonds between base pairs, creating the replication fork.

In a dihybrid cross of two AaBb parents, what fraction of offspring show both dominant traits?9/16. Each gene gives 3/4 dominant offspring independently, and 3/4 × 3/4 = 9/16.

How do the daughter cells from mitosis and meiosis differ in chromosome number?Mitosis produces two diploid cells identical to the parent. Meiosis produces four haploid cells, which is why it makes gametes.

Frequently asked questions

How often should I quiz myself while studying?

Short, frequent sessions tend to work better than one long cram session. Revisiting the same questions over several days helps material stick.

Does quizzing myself help with memorizing terms in a course like biology?

Yes. Retrieval practice, which means answering from memory before checking, is one of the better-supported ways to remember terms and concepts.

Can I export my quizzes?

Exports are a paid feature. Plus includes PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML.

Is there a free plan?

Yes. The free plan includes 3 generations per month and studying in the browser, and no credit card is needed to start. Students get 40% off with a school email.
