Explain the physiological process mentioned above.
Topic: Explanation of photosynthesis
Answer
PHOTOSYNTHESIS is the process by which living plant cells containing CHLOROPHYLL manufacture food — glucose and starch — from the simple inorganic raw materials CARBON DIOXIDE and WATER, using the energy of SUNLIGHT. OXYGEN is released as a by-product.
A complete answer needs FIVE elements, and each is a place where a mark can be lost: GREEN plant cells containing CHLOROPHYLL raw materials — CARBON DIOXIDE and WATER energy source — SUNLIGHT product — GLUCOSE (stored as starch) by-product — OXYGEN
Candidates most often omit WATER, or say "plants" without "green".
The word itself summarises it: PHOTO (light) + SYNTHESIS (building up) — building food using light.
