Pick an option and check your answer. The full worked answer is below either way.
Answer
(d) It is the synthesis of glucose from carbon dioxide and water by green plants using light energy..
A complete definition needs FOUR elements, and only option (d) has all of them: the product — GLUCOSE BOTH raw materials — CARBON DIOXIDE and WATER the organism — GREEN plants (they must have chlorophyll) the energy source — LIGHT
Check each wrong option against that list: (a) says NON-GREEN plants, and omits water — two faults (b) omits WATER (c) says NON-GREEN plants
A plant without chlorophyll cannot photosynthesise at all, which is why "green" is not decoration but part of the definition — and is exactly what the variegated-leaf experiment demonstrates.
WHEN OPTIONS ARE NEARLY IDENTICAL, list the elements a correct answer must contain and tick them off against each option. It is faster than reading four long sentences repeatedly.
