Example class 12 biology quiz questions

Which enzyme fixes carbon dioxide in the Calvin cycle?RuBisCO attaches CO2 to RuBP, which is the first step of carbon fixation.

True or false: the leading strand during DNA replication is synthesized continuously.True. DNA polymerase adds nucleotides 5' to 3', so the leading strand grows continuously toward the replication fork while the lagging strand forms in Okazaki fragments.

In a monohybrid cross between two Aa parents, what fraction of offspring are aa?One in four. The Punnett square gives 1 AA : 2 Aa : 1 aa, so only one quarter are homozygous recessive.

Which hormone lowers blood glucose levels?Insulin, secreted by the beta cells of the pancreas. It promotes glucose uptake into cells and its storage as glycogen.

Which organelle is the site of photosynthesis in plant cells?The chloroplast. It contains chlorophyll, which captures light energy for the light reactions and the Calvin cycle.

Generate the full set

Built from your material

Questions come from the PDF, slides, notes or page photos you upload, so they follow the chapters your teacher actually covered.

Explanations for every answer

Each question shows why the correct answer is right, so a wrong guess becomes a lesson instead of a dead end.

Spaced review

Missed questions can return on a schedule, so the topics you find hard come back before the exam.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file or a photo of a textbook page.

Choose a question type

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

Answer and review

Work through the questions, read each explanation and redo the ones you missed.

Each question comes with an explanation, which matters in biology because many wrong options sound close to right. Reading why the correct answer fits helps you learn the process, such as the steps of mitosis or the path of blood through the heart, not just the answer letter.

Short quizzes spread over several days tend to work better than one long session before the exam. Retake the questions you missed, and generate a fresh set from the next chapter as you go.
