Question { 5699 }

Do red algae perform photosynthesis?

Answer

Red algae are
red because they
contain pigments
called
phycoerythrins
which absorbs
blue light and
reflects red
light.
This makes it
possible for red
algae to carry
out
photosynthesis
in comparatively
deep waters,
because blue
light penetrates
deeper than
lights of longer
wavelengths,
such as red
light.
Some red algae
only contain a
very small
amount of
phycoerythrins
and such species
can look green
or bluish rather
than red.
