Why don't flower pigments dissolve when they become wet with rain?

Answer 1

Because the pigments are contained inside cells. The cell walls separate the contents of the cell from the wet rain on the outside - you will notice that the underside of the flower does not get wet - well the surface of the top side is waterproof - this is caused by the protection of the cell walls.

Answer 2

Flower pigments are insoluble in water, which means they do not dissolve when they come into contact with rain. The pigments are usually embedded within the cells of the flower petals or in specific structures, making them resistant to water. Additionally, the chemical composition of these pigments allows them to maintain their color and structure even when wet.
