Read the passage from "Carrots with Character," which is an informational text about the health benefits
of genetically modified carrots.
The researchers, led by plant geneticist Philipp Simon,
haven't limited themselves to the color orange.
They've selectively bred a rainbow of carrots--purple,
red, yellow, even white. Scientists are learning that
these plant pigments perform a range of protective
duties in the human body--which is not surprising,
says Simon, since many of the pigments serve to
shield plant cells during photosynthesis.
Red carrots derive their color mainly from lycopene, a
type of carotene believed to guard against heart
disease and some cancers. Yellow carrots accumulate
xanthophylls, pigments similar to beta-carotene that
support good eye health. Purple carrots possess an
entirely different class of pigments --anthocyanins-
which act as nowerful antioxidants
