Question 1 · 1 mark · Difficulty 1/3

Which gel-like substance fills the cell and is where many chemical reactions occur?

  1. Nucleus
  2. Cytoplasm
  3. Cell membrane
  4. Cell wall
Show answer & explanation
✓ Answer: B — Cytoplasm
The cytoplasm is the jelly-like fluid where most of the cell's chemical reactions take place and where the organelles are suspended.
Question 2 · 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: B — Transporting 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.

AQA GCSE Biology: Cell structure and function FAQ

Is Kramizo free for AQA GCSE 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 structure and function practice with other Biology topics or even switch to a totally different AQA 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 structure and function questions aligned to the official AQA GCSE Biology syllabus?
Every question is written against the published AQA GCSE Biology specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real AQA 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 AQA.
How is Cell structure and function typically tested on AQA GCSE Biology papers?
Cell structure and function appears across multiple question types on real AQA GCSE 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.
