Question 1 · 1 mark · Difficulty 1/3

Which of the following is the correct word equation for photosynthesis?

  1. carbon dioxide + glucose → water + oxygen
  2. carbon dioxide + water → glucose + oxygen
  3. water + oxygen → glucose + carbon dioxide
  4. glucose + oxygen → carbon dioxide + water
Show answer & explanation
✓ Answer: Bcarbon dioxide + water → glucose + oxygen
Photosynthesis converts carbon dioxide and water, using light energy, into glucose and oxygen. Option A is the word equation for aerobic respiration, not photosynthesis. Option C incorrectly places glucose as a reactant. Option D places oxygen as a reactant, which is the role of oxygen in respiration.
Question 2 · 1 mark · Difficulty 1/3

Which tissue in a leaf is responsible for the majority of photosynthesis?

  1. Xylem vessels
  2. Lower epidermis
  3. Spongy mesophyll
  4. Palisade mesophyll
Show answer & explanation
✓ Answer: DPalisade mesophyll
The palisade mesophyll cells are tightly packed near the upper surface of the leaf and contain the greatest number of chloroplasts per cell, making them the primary site of photosynthesis. The lower epidermis (option A) is largely protective and lacks chloroplasts. The spongy mesophyll (option B) contains some chloroplasts but fewer than palisade cells and is primarily adapted for gas exchange. Xylem vessels (option D) are vascular tissue that transport water and minerals, not involved in photosynthesis.

CIE IGCSE Co-ordinated Science (Double Award): Plant nutrition and photosynthesis FAQ

How many CIE IGCSE Co-ordinated Science (Double Award) questions on Plant nutrition and photosynthesis are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Plant nutrition and photosynthesis for CIE IGCSE Co-ordinated Science (Double Award), 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 CIE 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 CIE IGCSE students preparing for Co-ordinated Science (Double Award)?
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 nutrition and photosynthesis practice with other Co-ordinated Science (Double Award) topics or even switch to a totally different CIE 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 nutrition and photosynthesis questions aligned to the official CIE IGCSE Co-ordinated Science (Double Award) syllabus?
Every question is written against the published CIE IGCSE Co-ordinated Science (Double Award) specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CIE 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 CIE.
How is Plant nutrition and photosynthesis typically tested on CIE IGCSE Co-ordinated Science (Double Award) papers?
Plant nutrition and photosynthesis appears across multiple question types on real CIE IGCSE Co-ordinated Science (Double Award) 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.
