A student observes a microorganism under the light microscope and notes it has a defined nucleus, cell wall, and reproduces by spore formation. Which type of microorganism is most likely being observed?

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 student observes a microorganism under the light microscope and notes it has a defined nucleus, cell wall, and reproduces by spore formation. Which type of microorganism is most likely being observed?

Accepted Answer

A fungus — Fungi are eukaryotes with a membrane-bound nucleus, cell walls made of chitin, and many reproduce via spores. Viruses lack cellular structure entirely and cannot be seen with a light microscope at school level. Bacteria are prokaryotes with no membrane-bound nucleus. Protozoa are eukaryotes but generally lack a cell wall and do not reproduce by spore formation as their primary method.

A protozoan
