Which pigment is responsible for red colour of tomato?

Question

Accepted Answer

The correct answer is **Option 4: Lycopene**.

Here's a detailed explanation:

**Why Option 4 (Lycopene) is correct:**

Lycopene is a bright red carotenoid pigment and phytochemical found in tomatoes and other red fruits and vegetables, such as watermelons, pink grapefruits, and papayas. It is the primary pigment responsible for the characteristic vibrant red color of ripe tomatoes. Lycopene is also a powerful antioxidant, which contributes to the health benefits associated with consuming tomatoes.

**Why other options are incorrect:**

*   **Option 1: Xanthophyll**
    Xanthophylls are also carotenoid pigments, but they are typically responsible for yellow, orange, or brown colors in plants (e.g., corn, egg yolks, autumn leaves). While xanthophylls are present in tomatoes, they are not the primary pigment that gives tomatoes their distinct red color. Lycopene dominates the red hue.

*   **Option 2: Anthocyanin**
    Anthocyanins are flavonoid pigments that produce red, purple, and blue colors in many fruits, vegetables, and flowers (e.g., blueberries, blackberries, red cabbage, grapes). While some specialized varieties of tomatoes have been bred to produce anthocyanins, resulting in purple or black tomatoes, the typical red color of common tomatoes is *not* due to anthocyanins. The dominant red pigment in standard red tomatoes is lycopene.

*   **Option 3: Cyanide**
    Cyanide is a highly toxic chemical compound and is not a pigment. It has no role in providing color to plants or any biological organism. Its presence in food would be extremely dangerous and is unrelated to natural coloration.
