Cloning – Plant and Animal Cloning — CXC CSEC Biology Practice

Q: How many CXC CSEC Biology questions on Cloning – Plant and Animal Cloning are there on Kramizo?

Kramizo currently has 20 exam-board-aligned practice questions on Cloning – Plant and Animal Cloning 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.

Q: 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 Cloning – Plant and Animal Cloning 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.

Q: Are the Cloning – Plant and Animal Cloning 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.

Q: How is Cloning – Plant and Animal Cloning typically tested on CXC CSEC Biology papers?

Cloning – Plant and Animal Cloning 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.

Question 1

A Guyanese research facility uses embryo splitting to clone cattle with desirable meat production traits. At which stage must the embryo be split to produce viable clones?

Accepted Answer

At the early stage when cells are still totipotent — At the early stage when cells are still totipotent. Award 1 mark for B. Totipotent cells can differentiate into any cell type and form a complete organism. Embryo splitting must occur at the early stage (usually 2-8 cell stage) before cell specialization begins. A is incorrect because specialized cells cannot form a complete organism. C is incorrect because splitting after implantation would damage the developing embryo. D is incorrect because organ formation indicates advanced differentiation.

Answer

After the cells have specialized into different tissue types

Answer

At the early stage when cells are still totipotent

Answer

After implantation in the uterus

Answer

When the embryo has formed organs

Question 2

A farmer in Jamaica uses tissue culture to produce disease-free banana plants for commercial production. Which part of the plant is most commonly used to initiate this cloning process?

Accepted Answer

Meristem tissue — Meristem tissue. Award 1 mark for B. Meristem tissue contains undifferentiated cells capable of rapid division and differentiation into all plant tissues. A is incorrect because root tips, while containing meristematic cells, are not the preferred source for tissue culture due to contamination risk. C is incorrect because mature leaf cells are differentiated and less suitable for regeneration. D is incorrect because stem bark consists of dead protective tissue unsuitable for cloning.

Answer

Root tips

Answer

Meristem tissue

Answer

Mature leaf cells

Answer

Stem bark
