Final answer:
To explore photosynthesis, you should measure oxygen production and carbon dioxide consumption because they indicate the plant's photosynthetic activity. Option C is correct.
Step-by-step explanation:
To explore photosynthesis in plants, you would need to measure oxygen production and carbon dioxide consumption. These are crucial parameters that reflect the photosynthetic activity as plants use carbon dioxide to produce glucose and release oxygen as a byproduct. Specifically, the chloroplasts within plant cells facilitate the conversion of light energy into chemical energy, producing sugars/carbohydrates and oxygen in the process.
When assessing photosynthesis, it is also pertinent to understand the reactants and products involved. The necessary reactants for photosynthesis are carbon dioxide and water, and with the addition of sunlight, the photosynthesis process yields glucose and oxygen. The gross primary productivity of an ecosystem could be evaluated by measuring the rate at which plants convert these reactants into glucose and oxygen.
In experimental setups under different colored lights, the plants would exhibit varying growth patterns due to the different absorption spectra of chlorophyll a and b. Typically, plant growth would be more substantial under blue light, which is absorbed effectively by chlorophyll, followed by red light and then green light, which is reflected rather than absorbed by the chlorophyll pigments.
