Question 1 · 1 mark · Difficulty 1/3

A farmer in St. Elizabeth, Jamaica, noticed that his callaloo plants wilted during the hottest part of the day but recovered by evening. Which process is primarily responsible for the wilting?

  1. Photosynthesis
  2. Transpiration
  3. Respiration
  4. Translocation
Show answer & explanation
✓ Answer: BTranspiration
Award 1 mark for identifying transpiration as the process causing water loss faster than uptake during hot conditions. A is incorrect — photosynthesis produces glucose, not water loss. C is incorrect — respiration releases energy but does not cause wilting. D is incorrect — translocation moves sugars, not water loss from leaves.
Question 2 · 1 mark · Difficulty 1/3

Which structure in a plant root is responsible for increasing the surface area for water absorption?

  1. Xylem vessel
  2. Root hair cell
  3. Guard cell
  4. Phloem tube
Show answer & explanation
✓ Answer: BRoot hair cell
Award 1 mark for identifying root hair cells as extensions that increase surface area. A is incorrect — xylem vessels transport water upward, not absorb it. C is incorrect — guard cells control stomatal opening in leaves. D is incorrect — phloem tubes transport sugars, not water uptake.

CXC CSEC Integrated Science: Transport in Organisms FAQ

How many CXC CSEC Integrated Science questions on Transport in Organisms are there on Kramizo?
Kramizo currently has 68 exam-board-aligned practice questions on Transport in Organisms for CXC CSEC Integrated 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 Integrated 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 Transport in Organisms practice with other Integrated 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 Transport in Organisms questions aligned to the official CXC CSEC Integrated Science syllabus?
Every question is written against the published CXC CSEC Integrated 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 Transport in Organisms typically tested on CXC CSEC Integrated Science papers?
Transport in Organisms appears across multiple question types on real CXC CSEC Integrated 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.
