Q: How do I try a free CIE Biology question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CIE IGCSE Biology bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CIE Biology students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Biology questions aligned to the CIE IGCSE syllabus?

Every question is written against the published CIE IGCSE Biology syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CIE past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

Which of the following best explains why leaves are typically broad and flat?

Accepted Answer

B. To provide a large surface area for light absorption and gas exchange — The broad, flat shape of most leaves maximises the surface area exposed to sunlight for light absorption and provides a large area across which gas exchange can occur through stomata. A larger volume for water storage would not require a flat shape, and broad leaves are actually more susceptible to wind damage rather than resistant to it.

Answer

C. To allow the leaf to withstand strong wind without tearing

Answer

A. To increase the volume of cells available for water storage

Answer

D. To reduce the distance that water must travel through xylem vessels

Answer

B. To provide a large surface area for light absorption and gas exchange
