Describe the function of photosynthetic pigments.
State the exact location of photosynthetic pigments within a chloroplast.
Name a practical method used to separate photosynthetic pigments.
With reference to Fig. 1.2, explain the pattern of results from $0.25\ \text{mol dm}^{-3}$ to $1.25\ \text{mol dm}^{-3}$ in sodium hydrogencarbonate solution.
For $C.\ caroliniana$ at $0.00\ \text{mol dm}^{-3}$ of sodium hydrogencarbonate solution, the percentage change in dissolved oxygen is negative. Suggest reasons for this negative result.
To reduce temperature changes, the student chose an LED lamp as the light source. LED lamps give off very little heat energy. Explain why minimising temperature changes matters in this experiment.
