Q: How do I try a free CXC Human and Social 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 Human and Social 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 Human and Social 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 Human and Social Biology questions aligned to the CXC CSEC syllabus?

Every question is written against the published CXC CSEC Human and Social 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

A Jamaican student studying the sugarcane plant notices that water moves upward from the roots through long, hollow, dead cells joined end to end. These cells form which type of tissue?

Accepted Answer

Xylem tissue — Award 1 mark for xylem tissue. Xylem vessels are composed of dead cells with lignified walls that form hollow tubes for the transport of water and dissolved mineral salts from roots to leaves. A is incorrect — phloem tissue transports dissolved sugars (not water) and is composed of living sieve tube cells. C refers to animal tissue lining surfaces. D is the photosynthetic tissue in leaves, not a transport tissue.

Answer

Mesophyll tissue

Answer

Phloem tissue

Answer

Epithelial tissue
