Question 1 · 1 mark · Difficulty 1/3

Which of the following is a genetically modified organism (GMO)?

  1. A mango tree grown from a seed
  2. A pig bred for larger size
  3. Bt cotton containing bacterial genes
  4. A banana plant grown from a sucker
Show answer & explanation
✓ Answer: CBt cotton containing bacterial genes
Award 1 mark for identifying that GMOs contain genes from a different species inserted using genetic engineering. A is incorrect — seed-grown mangoes are produced by natural reproduction. B is incorrect — selective breeding does not involve gene transfer between species. D is incorrect — vegetative propagation produces clones but does not involve genetic modification.
Question 2 · 1 mark · Difficulty 1/3

A farmer in Trinidad wishes to produce many identical plantlets of a high-yielding cassava variety in a short time. Which biotechnology technique would be MOST suitable for this purpose?

  1. Tissue culture
  2. Artificial insemination
  3. Selective breeding
  4. Cross-pollination
Show answer & explanation
✓ Answer: ATissue culture
Award 1 mark for identifying tissue culture as the technique that produces genetically identical plants (clones) rapidly from small pieces of plant tissue. B is incorrect — artificial insemination is used in animal reproduction, not plant propagation. C is incorrect — selective breeding takes multiple generations and does not produce identical offspring. D is incorrect — cross-pollination produces genetic variation, not identical plants.

CXC CSEC Agricultural Science: Agricultural Biotechnology FAQ

How many CXC CSEC Agricultural Science questions on Agricultural Biotechnology are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Agricultural Biotechnology for CXC CSEC Agricultural Science, 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 Agricultural Science?
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 Agricultural Biotechnology practice with other Agricultural Science 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 Agricultural Biotechnology questions aligned to the official CXC CSEC Agricultural Science syllabus?
Every question is written against the published CXC CSEC Agricultural Science 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 Agricultural Biotechnology typically tested on CXC CSEC Agricultural Science papers?
Agricultural Biotechnology appears across multiple question types on real CXC CSEC Agricultural Science 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.
