The production of starch, and not glucose, is used as a measure of photosynthesis in variegated leaves because_____________
a) Starch is a long-term storage molecule, indicating sustained photosynthetic activity.
b) Glucose is rapidly metabolized for energy, making it unreliable for measuring photosynthesis.
c) Starch accumulates in chloroplasts during daylight hours, providing a more accurate indicator.
d) Glucose levels fluctuate due to metabolic processes other than photosynthesis.
