Q: How do I try a free CXC 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 CXC CSEC 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 CXC 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 CXC CSEC syllabus?

Every question is written against the published CXC CSEC 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 CXC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

In a breadfruit tree growing in Jamaica, which part of the plant would function as a 'sink' during fruit development?

Accepted Answer

Developing breadfruit — Award 1 mark for developing breadfruit. A sink is any region that uses or stores organic substances. Developing fruits are strong sinks as they require sugars for growth and starch storage. A is incorrect because mature leaves are sources, producing sugars by photosynthesis. B and D, while also sinks, are not the best answer in the context of fruit development when fruits become the primary sink.
