Question 1 · 1 mark · Difficulty 1/3

A student in Trinidad examined a cross-section of a mango leaf under a microscope. She observed tightly packed cells near the upper surface and loosely arranged cells near the lower surface. The tightly packed cells are called:

  1. Spongy mesophyll
  2. Palisade mesophyll
  3. Guard cells
  4. Epidermal cells
Show answer & explanation
✓ Answer: BPalisade mesophyll
Award 1 mark for correct identification. Palisade mesophyll cells are columnar, tightly packed, and located near the upper epidermis to maximise light absorption for photosynthesis. A is incorrect — spongy mesophyll is loosely arranged with air spaces. C is incorrect — guard cells surround stomata. D is incorrect — epidermal cells form the outer protective layer.
Question 2 · 1 mark · Difficulty 1/3

Cassava, a staple crop in many Caribbean countries, has swollen tuberous roots. What is the main substance stored in these roots?

  1. Proteins
  2. Lipids
  3. Starch
  4. Cellulose
Show answer & explanation
✓ Answer: CStarch
Award 1 mark for identifying starch as the main storage carbohydrate in cassava roots. Cassava is processed to make cassava flour and is an important source of carbohydrates in the Caribbean diet. A is incorrect — cassava roots have low protein content. B is incorrect — lipids are not the main storage compound. D is incorrect — cellulose is a structural compound, not a storage compound.

CXC CSEC Agricultural Science: Plant Morphology and Physiology FAQ

How many CXC CSEC Agricultural Science questions on Plant Morphology and Physiology are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Plant Morphology and Physiology 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 Plant Morphology and Physiology 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 Plant Morphology and Physiology 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 Plant Morphology and Physiology typically tested on CXC CSEC Agricultural Science papers?
Plant Morphology and Physiology 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.
