Phaeophyta (Brown Algae) Phaeophyta or brown algae are a group of autotrophic, multicellular organisms, belonging to the class Phaeophyceae in the division Chromophyta. They contain the xanthophyll pigment - fucoxanthin, in addition to chlorophyll a and c. Hence, the members of phaeophyta exhibit a characteristic greenish-brown color.

Algae: Protists with Chloroplasts Algae are distinguished on a number of different characteristics. The most important ones are: 1  the colour of the plastids (more correctly the combination of photosynthetic pigments that are present in the plastid). 2  the presence of flagella (and if so how many, how do they insert in the cell and how do they beat).

Phaeophyceae: Brown Algae Characteristics. The brown colour of these algae results from the dominance of the xanthophyll pigment fucoxanthin, which masks the other pigments, Chlorophyll a and c (there is no Chlorophyll b), beta-carotene and other xanthophylls. Food reserves are typically complex polysaccharides, sugars and higher alcohols.

Rheumatoid Factor Immunoglobulin M (IgM) autoantibodies against the Fc fragment of immunoglobulin G (IgG) are called rheumatoid factors (RFs). These proteins are produced by B cells and can be found circulating in the blood. Their role is unknown in both healthy individuals and in those with rheumatoid arthritis.

- There are also a few organisms that look like algae but are not algae at all. In a healthy aquarium, the algae will be green, and if left alone, will grow hair-like in appearance. Algae that is red or brown may indicate a water quality problem, such as high dissolved nitrate or phosphate levels in the water.

Getting Rid of Green Hair Algae Green Hair Algae (abbreviated as GHA for this article) - Derbesia-is a form of algae that looks like its name. It is usually dark green, grows quite long if left unattended and spreads across your tank rapidly. Once this problem has begun, it can get out of hand in a matter of weeks.

What is the other name for brown algae? This is one of the few areas where a large biomass of brown algae may be found in tropical waters. Many brown algae such as members of the order Fucales are commonly found along rocky seashores. Some members of the division are used as food for humans.est Answer: The Heterokontophyta (Phaeophyta or brown algae, singular: brown alga) is a large group of mostly marine multicellular algae, including many seaweeds of colder Northern Hemisphere waters.

Brown algae The closest relatives of the brown algae include unicellular and filamentous species, but no unicellular species of brown algae are known. However, most scientists assume that the Phaeophyceae evolved from unicellular ancestors.he particular shade depends upon the amount of fucoxanthin present in the alga. Second, all brown algae are multicellular. There are no known species that exist as single cells or as colonies of cells, and the brown algae are the only major group of seaweeds that does not include such forms.

Algae Blooms associated with phytoplankton (microscopic algae) turn the water a certain color. Algae blooms are commonly green, but they can also appear blue-green, brown, red, or violet. Other blooms form clumps or dense mats that float on the surface of the water, grow attached to the bottom, or attach to plants.

- Even some of the lower fungi belong to the brown seaweed family. Green algae have the greatest need for light, so they grow where the water is shallow, or even in the intertidal zone. They are a bright, vivid green. Our land plants are descended from a group of them.

Brown Algae UNICELLULAR OOORRRRR MULTICELLULAR?????? i cant find the answer in my SCIENCE BOOOOK!!!! SOO HELP! All brown algae are multicellular. Although some of the larger species such as the giant kelps appear to have stems and leaves, they are not true stems and leaves such as those found in the vascular plants, because they do not contain true vascular tissue.

3 Types of Sea Weed (Marine Algae) Brown algae is the largest type of algae. Brown algae is in the phylum Phaeophyta, which means dusky plants.. Brown algae is brown or yellow-brown in color and found in temperate or arctic waters. Brown algae typically have a root-like structure called a holdfast to anchor the algae to a surface.

Why are blue green algae prokaryotic? Because the cyanobacteria (the blue-green algae) have very large cells and a green color, they were assumed to be algae. But, we now know they are actually a type of bacteria, and thus, prokaryotes. They lack membrane bound organelles, including a nucleus, and they have circular DNA. Molecular biology has also now shown that their genetics clearly place them among the bacteria, not the algae.

- There is no generally accepted definition of algae. One definition is that algae have chlorophyll as their primary photosynthetic pigment and lack a sterile covering of cells around their reproductive cells. Some authors exclude all prokaryotes and thus do not consider cyanobacteria (blue-green algae) as algae.

- Brown seaweeds-the most complex algae. A myriad of coloursThere are many types of algae, but three of the main divisions are the green-algae or Chlorophyta (like Volvox, Chlamydomonas, Spirogyra, Scenedesmus and Ulva), the brown algae and the red algae.ach ball, or coenobium, consists of a single layer of superficial cells-it is a colony of cells. Each cell is surrounded by a thick mucilaginous wall, forming an enclosing cell. In some species, these mucilaginous walls may extend toward the centre of the ball and almost completely fill it.

Phaeophyceae: Brown Algae In some areas, like the west of Ireland and Scotland, kelps and other brown algae are gathered as a fertiliser for land. There are about 1800 species of brown algae, and most are marine. In general, brown algae are larger and more species are found in colder waters.Virtually all the biomass worldwide comes from a relatively small number of species in the orders Laminariales and Fucales.haracteristics. The brown colour of these algae results from the dominance of the xanthophyll pigment fucoxanthin, which masks the other pigments, Chlorophyll a and c (there is no Chlorophyll b), beta-carotene and other xanthophylls.

- What are blue-green algae (cyanobacteria)? Cyanobacteria, formerly called blue-green algae are relatively simple, primitive life forms closely related to bacteria. Typically much larger than bacteria, they photosynthesize like algae. Depending upon the species, cyanobacteria can occur as single cells, filaments of cells, or colonies.
