What does the visual difference between purple and red tomatoes directly indicate about their composition?
Answer
A direct indicator of a chemical difference in the fruit's composition
The variance in appearance between a deep purple tomato and a standard red tomato is not merely superficial cosmetic variation; it is rooted in tangible biochemical differences within the fruit's structure. The shift in color from red (dominated by lycopene) to deep purple signals the incorporation of anthocyanins, representing an added layer of pigmentation derived from differing genetic expressions. Therefore, the striking visual difference serves as an immediate, concrete signal that there is a measurable chemical difference in the antioxidants present in the flesh and skin of the two types of fruit.
