      Macroscopic algae is better known as seaweed. An important ecological role that is shared by macroscopic algae is that it helps to clean the sea, prevents erosion and it serves as a food for fish.   Red algae gain their often brilliant colors thanks to the pigment phycoerythrin. The ability to absorb blue light allows red algae to live at greater depths than either brown or green algae. Coralline algae, a subgroup of red algae, is important in the formation of coral reefs.

      The brown algae of the genus Fucus are widely distributed on the temperate rocky shores of the northern hemisphere, where they occur mainly in the intertidal zone (Graham and Wilcox ). In the brackish northern Baltic Sea, Fucus is the main genus of large canopy-forming macroalgae and it has an important role in providing shelter and food to Author: Henna Rinne, Sonja Salovius-Laurén.

Red algae are now widely accepted as plants - but only by the broadest definition of "plants", so acceptance isn't universal and is subject to.   Also found in the brown algal zone is a thin encrusting red alga (Rhodophyta) Hildenbrandia. This genus, that often covers a good portion of the substratum, is difficult to distinguish from the rock surface to which it tightly adheres. Other species of encrusting Blue-green bacteria, green brown and red algae may also be found.

6 Use of algae and aquatic macrophytes as feed in small-scale aquaculture – A review Another green filamentous alga, Hydrodictyon, commonly known as ‘water net’, belongs to the family Hydrodictyaceae and prefers clean, eutrophic water.

Its name refers to its shape, which looks like a netlike hollow sack (Figure ) and can growFile Size: KB. Like the brown algae, the red algae are almost entirely marine. Their size and complexity vary from thin films growing on rocks to complex filamentous and membranous forms growing to heights approaching one meter.

Most red algae are small, and none rival the giant kelps in size, but they occupy a greater range of depths than do the brown Size: KB. The brown algae (singular: alga), comprising the class Phaeophyceae, are a large group of multicellular algae, including many seaweeds located in colder waters within the Northern brown algae live in marine environments, where they play an important role both as food and as a potential instance, Macrocystis, a kelp of the order Laminariales, may reach 60 m ( ft Class: Phaeophyceae, Kjellman, Green Algae have the largest representation, mostly freshwater and terrestrial but many are also marine.

Yes, Brown algae differs from Red and Green algae because Brown algae is used as a thickener in alot of foods. Red and Green algae are used for most of the time for fish and other underwater.

INTRODUCTION. Brown algae, the Phaeophyceae (or Fucophyceae; Christensen, ), are a class (or division, Phaeo- phyta; Papenfuss, ) of algae consisting mainly of complex, macroscopic seaweeds whose brown color comes from a carotenoid pigment, fucoxanthin, and in some species, various phaeophycean tannins.

Some algae, the seaweeds, are macroscopic and may be confused with plants. Seaweeds can be red, brown, or green, depending on their photosynthetic pigments. Green algae, in particular, share some important similarities with land plants; however, there are also important distinctions. Key Difference – Red Algae vs Brown Algae.

Algae are large polyphyletic, photosynthetic organisms that contain a diverse group of species. They range from unicellular microalgae genera such as Chlorella to multicellular forms such as giant kelp and brown algae. They are mostly aquatic and autotrophic in nature.

They lack stomata, xylem, and phloem that are found in the land. Some algae, the seaweeds, are macroscopic and may be confused with plants. Seaweeds can be red, brown, or green, depending on their photosynthetic pigments.

Green algae, in particular, share some important similarities with land plants;. The algae are autotrophic protists that can be unicellular or multicellular. These organisms are found in the supergroups Chromalveolata (dinoflagellates, diatoms, golden algae, and brown algae) and Archaeplastida (red algae and green algae).

They are important ecologically and environmentally because they are responsible for the production of approximately 70% of the oxygen and organic .Brown algae, (class Phaeophyceae), class of about 1, species of algae in the division Chromophyta, common in cold waters along continental coasts.

Species colour varies from dark brown to olive green, depending upon the proportion of brown pigment (fucoxanthin) to green pigment (chlorophyll).Brown algae vary in form and size from small filamentous epiphytes (Ectocarpus) to complex giant.Red algae don't have flagellum, and brown algae have fucoxanthin which gives it it's brown pigment.

What characteristics of green algae have led scientists to conclude that this group includes the ancestors of land plants, most likely the charophytes?
