What is a function of chromoplasts?
Chromoplasts are plastids responsible for pigment synthesis and
storage. They, like all other plastids (including chloroplasts and
leucoplasts), are organelles found in specific photosynthetic
eukaryotic species.
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.
