A researcher studying breadfruit trees in Jamaica examines the cambium layer, which produces new xylem and phloem cells. The cambium consists of actively dividing cells that are similar in structure and function. What level of organisation does the cambium represent?

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

A researcher studying breadfruit trees in Jamaica examines the cambium layer, which produces new xylem and phloem cells. The cambium consists of actively dividing cells that are similar in structure and function. What level of organisation does the cambium represent?

Accepted Answer

Tissue — Award 1 mark for identifying that a group of similar cells performing the same function (cell division and production) represents tissue level. A is incorrect because organ systems comprise multiple organs. B is incorrect because the cambium is a component tissue within the stem organ. D refers to the whole tree.
