Question 1 · 1 mark · Difficulty 1/3

A student observing a sample of human blood under a microscope notices cells with no nucleus and a biconcave shape. These cells are specialised for which function?

  1. Fighting disease by producing antibodies
  2. Transporting oxygen around the body
  3. Clotting blood at wound sites
  4. Removing waste products from tissues
Show answer & explanation
✓ Answer: BTransporting oxygen around the body
Award 1 mark for identifying that red blood cells transport oxygen. The biconcave shape and lack of nucleus are adaptations that increase surface area for oxygen uptake and provide more space for haemoglobin. A is incorrect because white blood cells produce antibodies. C refers to platelets, not red blood cells. D is incorrect as this is not the primary function of red blood cells.
Question 2 · 1 mark · Difficulty 2/3

In Jamaica, farmers growing sugar cane often observe root hair cells under a microscope. Which structural feature of root hair cells increases the surface area for water absorption?

  1. A thick cell wall for support
  2. Long, finger-like projections extending from the cell
  3. Multiple nuclei in each cell
  4. A large number of chloroplasts
Show answer & explanation
✓ Answer: BLong, finger-like projections extending from the cell
Award 1 mark for identifying the long projection. Root hair cells have a hair-like extension that significantly increases surface area for water and mineral uptake from the soil. A is incorrect as the thick cell wall is not the primary adaptation for absorption. C is incorrect as root hair cells have one nucleus. D is incorrect because root hair cells lack chloroplasts as they are underground.

CXC CSEC Biology: Cell Specialisation and Organisation FAQ

How many CXC CSEC Biology questions on Cell Specialisation and Organisation are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Cell Specialisation and Organisation for CXC CSEC Biology, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CXC paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CXC CSEC students preparing for Biology?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Cell Specialisation and Organisation practice with other Biology topics or even switch to a totally different CXC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Cell Specialisation and Organisation questions aligned to the official CXC CSEC Biology syllabus?
Every question is written against the published CXC CSEC Biology specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC.
How is Cell Specialisation and Organisation typically tested on CXC CSEC Biology papers?
Cell Specialisation and Organisation appears across multiple question types on real CXC CSEC Biology papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
