red algae

red algae Taxonomic group (phylum) of reddish algae, the Rhodophyta. They are numerous in tropical and subtropical seas. Most are slender, branching seaweeds that form shrub-like masses. Some become encrusted with calcium carbonate and are important in reef formation. Rhodophytes have red and purplish pigments, which absorb light for photosynthesis. They also have chlorophyll. They have complex life cycles with two or three stages, involving alternation of generations.
