Algae are basically vascular plants that come in a variety of shapes, forms, sizes, and colors.The major group of algae is the brown algae which are present in distinct shades of color in their habitat. Most brown algae are marine algae, which means we find them in aquatic environments.When compared to other algae, these are dark brown in color. Conspicuous algae are known for their conspicuous offshore growths. In form, the brown algae range from small crusts or cushions to leafy free-floating mats. They’re regarded as a crucial aspect of the ocean, although few people are aware of their importance in marine ecosystems.In fact, many people believe they do nothing but destroy the environment, as evidenced by the dark green water on the beach. No doubt many of us have referred to algae as murky and dirty, but there is a significance of algae in our ecosystem.Read on to learn more about the known species of algae that are of brown color in appearance compared to other types of algae.The Basic Characteristics Of Brown AlgaeBrown algae is a member of Phaeophyceae, a class of algae. The algae of this class are brown in color due to the presence of pigment in them called fucoxanthin.Brown algae can be found in over 2000 different species. Many animals and marine life rely on brown algae for food and shelter. Humans consume brown algae too.The giant kelp Macrocystis is a brown alga that may reach a length of 196.9 ft (60 m) and forms underwater forests.Brown algae bloom abundantly on the rocks along the coast.Brown algae are all multicellular organisms. The plant’s body is thallus, which means it doesn’t have genuine roots, stems, or leaves. Algae are commonly found in damp environments.We find the majority of brown algae in the sea. We can find them in chilly coastal waters. They can either float freely or be linked to the substratum.Algae help to oxygenate Earth’s atmosphere. If all of Earth’s algae died tomorrow, we would perish as well. Algae produce half of the oxygen we inhale.Asexual and sexual reproduction is also possible in algae. Spore creation is used for asexual reproduction.Although certain algae can create a symbiotic relationship with other creatures, algae are self-contained.The Uses And Health Benefits Of Brown AlgaeBecause of their ability to fix carbon, algae is important. They are integral primary producers of the aquatic food chain. Some very essential uses of brown algae are as follows.Brown algae like Laminaria, Sargassum are used to prepare edible seaweed. Seaweed helps control our thyroid function. Seaweed is unique in that it can absorb a significant amount of iodine from the ocean. Among the best sources of iodine is kelp. Tyrosine is an amino acid found in seaweed that, combined with iodine, is required to generate two important hormones that help the thyroid gland function effectively.Antioxidants found in seaweed prepared by the use of brown algae include vitamins A, C, and E, as well as carotenoids and flavonoids. Our cells are protected against oxidative damage by these antioxidants.Brown algae includes both fiber and carbohydrates, which can be used as food by the microorganisms in our gut. This fiber can also help to nourish your gut by promoting the growth of ‘healthy’ bacteria.Seaweed may aid weight loss because of its low-calorie content, filling fiber, and fucoxanthin, which leads to a faster metabolism.Alginic acid is extracted commercially and used in the food business as a thickening agent. Brown algae acid is used as a stabilizer in the ice cream and baking industries. Agar or agar-agar is the thickening agent most commonly used in ice cream.Kelp can produce dense forests with great productivity, biodiversity, and ecological value. One such example is a forest located along the Norwegian coast, which is home to many creatures. This forest covers 2,240 sq mi (5,800 sq km).Alginic acids found in brown algae are used in batteries. Lithium-ion batteries employ one of these products. A major component of a battery anode is alginic acid. This polymer is present in large amounts in brown algae but not in land plants.Some Side Effects Of Brown AlgaeDespite algae being a huge source of nutrients including protein and vitamins, it’s not without its share of side effects.It is possible that some people are allergic to algae. Using brown algae may cause rashes, breathing difficulties, swelling, and anaphylaxis. Goiter, skin rashes, and gastrointestinal problems are all potential side effects.Ingestion of excessive amounts of dried seaweed may raise the quantity of thyroid-stimulating hormone in the body, giving your complexion a yellow color or causing a skin outbreak that appears like acne.Laminaria, brown algae, can enlarge the cervix and cause preterm labor among pregnant women. Pregnant women should avoid eating brown algae.Toxins are produced naturally by a small fraction of algae species, which can be toxic to animals who eat them. Algal blooms can lead to an increase in the number of harmful algae species. Thousands of fish, sea turtles, and marine animals have died because of these accidents.It’s important to be cautious if we want to avoid sickness. But algae grows easily in a marine environment. The marine environment does not necessarily have to be an ocean. It can be our aquarium or our saltwater tank.It’s important to regularly change the water, otherwise, it can extinguish the food of nitrate and phosphate for brown algae. Fish including hillstream loach and amano shrimp can eat brown algae in the tank.The Different Categories Of AlgaeHere are the different categories of algae that can be found in the wild: -Euglenophyta (Euglenoids): live in both fresh and saltwater. They don’t have a cell wall and are instead protected by a protein-rich layer known as the pellicle.Chrysophyta (golden-brown algae and Diatoms): there are over 100,000 different species of unicellular algae, making them the most common.Pyrrophyta (fire algae): these live in saline water, with a few species also living in freshwater. They create a neurotoxin that is toxic to humans and other animals.Chlorophyta (green algae): typically found in a variety of aquatic ecosystems, particularly freshwater areas. Green algae can process their own food since they have chloroplasts.Rhodophyta (red algae): this type of algae can be seen in some seaweeds. They are eukaryotic cells that lack flagella and centrioles and can be found primarily in tropical waters.Phaeophyta (brown algae): these algae are among the largest and most complicated on the planet. They live in various sea habitats.Xanthophyta (yellow-green algae): these are the least prolific algal species. They form their cell walls of silica and cellulose because their chloroplasts lack pigmentation, they seem paler green.Relationships Amongst The Algal GroupsBiotic interactions are the foundation of life’s diversity and the key to comprehending its complexity and persistence within an ecological niche.Most algae dwell in watery settings that are highly diverse and offer distinct conditions for the algae. Only single-celled green algae that live in damp places and lichens are the exception to this. Temperature, carbon dioxide, or oxygen concentrations, acidity, and turbidity are just a few of the circumstances that algae have developed to thrive under.Algae also live on land, thus the diversity of algae doesn’t stop there. When they form symbiotic partnerships, they can survive even when most of the other members of the group can’t. Most algae are autotrophs, which means they make their own food through photosynthesis. Some algae species are heterotrophic, meaning they get their nutrients from organic matter.The Difference Between Algae And FungiAlgae are autotrophic organisms. They are capable of photosynthesis because of their content of chlorophyll. Fungi, on the other hand, are heterotrophic. This means they rely on others for their nutritional needs. They eat organic matter that has died or is rotting.Algae, plural for alga means seaweed. Fungi is derived from a fungus which means sponge. Both algae and fungi are kept in different plant kingdoms. Funi has a kingdom of its own, whereas algae is kept under the kingdom Protista.Interestingly, despite the difference, some fungi and algae live in a symbiotic relationship. One such example is Lichens. In this symbiotic relationship, the algal partner feeds the fungi, and the fungi feed the algae.
