Answer
White flowers do not contain coloured pigments. The bright colours of flowers and fruits come from plastids called chromoplasts, which contain pigments that may be yellow, orange or red. White flowers appear white because they lack these coloured pigments. They may contain colourless plastids called leucoplasts, which store food materials such as starch, oils or proteins but do not contain any pigment. Therefore, the white appearance is due to the absence of coloured pigments rather than the presence of a white pigment.
