Red algae | Marine, Seaweed, Rhodophyta | Britannica
Red algae, (division Rhodophyta), any of about 6,000 species of predominantly marine algae, often found attached to other shore plants. Their morphological range includes filamentous, branched, feathered, and sheetlike thalli. The taxonomy of the group is contentious, and organization of the
Red algae - Wikipedia
The majority of species (6,793) are Florideophyceae, and mostly consist of multicellular, marine algae, including many notable seaweeds. [5] [6] Red algae are abundant in marine habitats. [7] Approximately 5% of red algae species occur in freshwater environments, with greater concentrations in warmer areas. [8]
Rhodophyta - red seaweeds - SeaNet
Red algae are the most diverse group of seaweeds on temperate shores. Colors can range from rose red or maroon to dark red, brown, or even green depending on relative concentrations of photosynthetic pigments (chlorophyll, phycoerythrin, phycocyanin, allophycocyanin).
Red algae – characteristics, structure, reproduction, and examples
Depending on the color, algae could be roughly classified into green, brown, and red algae. What are Red Algae? The red algae include some of the most delicate and beautiful seaweed you can find in a tide pool. The red color of these algae results from their red pigments – phycobilins, which are absent in green algae.
Red algae: Current Biology - Cell Press
Sep 23, 2024 · The red algae are a morphologically diverse group of eukaryotic organisms that make up the most diverse and largest group of seaweeds found in the oceans today. In evolutionary terms, the red algae form a distinct phylum within the Archaeplastida (or Plantae) kingdom called the Rhodophyta, and thus share a common evolutionary origin with the ...

What Are Red Algae? - ThoughtCo
Jan 18, 2020 · Red algae are found around the world, from polar waters to the tropics, and are commonly found in tide pools and in coral reefs. They also can survive at greater depths in the ocean than some other algae, because the phycoerythrin's absorption of blue light waves, which penetrate deeper than other light waves do, allows red algae to carry out ...
Concise review on seaweed photosynthesis: From physiological …
Aug 1, 2023 · The seaweeds are pluricellular photosynthetic organisms, comprising Rhodophyta (red algae), Chlorophyta (green algae) and Phaeophyceae (brown algae) (Fig. 1), and constitute a diversified group with high morphological and biochemical variations [1].
Rhodophyta: Red algae - Seaweed
AlgaeBase dynamic species counts shows that there are about 10,000 species of seaweeds, of which about 6,500 are red algae (Rhodophyta), the vast majority of which are marine. These are found in the intertidal and in the subtidal to depths of up to 40, or occasionally, 250 m.
Biology of Seaweeds - ScienceDirect
Jan 1, 2016 · Seaweeds are usually classified based on their pigments into three broad groups: red (Rhodophyta), green (Chlorophyta), and brown (Phaeophyta) algae. The red seaweeds are more diverse with more than 7000 species, followed by brown and green seaweeds with 2030 and 600 marine species, respectively, although the brown algal thalli are largest.
