Dose white flowers have special pigment?

Chromoplasts, in the traditional sense, are found in coloured organs of plants such as fruit and floral petals, to which they give their distinctive colors.



This is always associated with a massive increase in the accumulation of carotenoid pigments.



The conversion of chloroplasts to chromoplasts in ripening tomato fruit is a classic example.



Leucoplasts are a category of plastid and as such are organelles found in plant cells. They are non-pigmented, in contrast to other plastids such as the chloroplast and the chromoplast.



Lacking pigments, leucoplasts are not green, so they are predictably located in roots and non-photosynthetic tissues of plants. They may become specialized for bulk storage of starch, lipid or protein and are then known as amyloplasts, elaioplasts, or proteinoplasts respectively. However, in many cell types, leucoplasts do not have a major storage function and are present to provide a wide range of essential biosynthetic functions, including the synthesis of fatty acids, many amino acids, and tetrapyrrole compounds such as haem. In general, leucoplasts are much smaller than chloroplasts and have a variable morphology, often described as amoeboid.



Extensive networks of stromules interconnecting leucoplasts have been observed in epidermal cells of roots, hypocotyls and petals.

Dose white flowers have special pigment?
White flowers have a chemical makeup that reflects all colors of light, so you see them as white.
Reply:What the others have said is good but some flowers have markings that we humans can't see but that are visible in the UV spectrum and can be seen by insect pollinators. So special pigments can still be present (but don't have to be).
Reply:Generally speaking, when we talk about pigments in flowers whether they be some type of cyanin or whatever, the white color comes from an absence of the pigment rather than a special form.
