Solve this multiple-choice question and choose the correct option.

Plant pigments: Identify the pigment responsible for most red, blue, and purple colours in plants. Full question: Most of the red, blue, and purple colours of flowers/fruits are due to which pigment group? Choose the correct option.

Difficulty: Easy

Anthocyanins
Chlorophylls
Carotenes
Xanthophylls
Phycoerythrin

Correct Answer: Anthocyanins

Explanation:

ConceptAnthocyanins are water-soluble flavonoid pigments located in vacuoles, producing red–purple–blue hues depending on pH and co-pigmentation.

ContrastChlorophylls → green; carotenes/xanthophylls → yellow–orange; phycoerythrin → red accessory pigment in red algae.

Final AnswerAnthocyanins.
