Plant nutrition — IGCSE Sciences - Co-Ordinated (0654) questions by topic
Comparing bubbles of gas released by an aquatic plant in light against in darkness, and stating or completing the balanced symbol equation for photosynthesis, are the two recurring tasks across the 5 plant nutrition questions from 2023 and 2024, worth 10 to 13 marks.
State, complete and calculate head the command words, with describe and identify appearing where the investigation's method or results must be interpreted rather than the equation reproduced. Because the photosynthesis equation must balance exactly to earn credit, drill the equation-completion questions here and submit each attempt for instant marking, so a missing reactant or an unbalanced formula is corrected before it recurs.
