Reaching heights of more than 100 feet (30 m), the giant kelp is the largest seaweed and the largest of all marine algae. It lives in cold, clear waters where it forms large, dense kelp forests that provide habitat for thousands of other marine species.
Which is the smallest algae?
The smallest algae, less than 3 μm in diameter, are the most abundant eukaryotes of the World Ocean. Their feeding on planktonic bacteria of similar size is globally important but physically enigmatic.
What is giant kelp used for?
Giant kelp is harvested as a source of algin, an emulsifying and binding agent used in the production of many foods and cosmetics, like ice cream, cereal and toothpaste. Pieces of decomposing kelp (known as detritus) sink to the depths of the ocean, providing food for deep-sea creatures.
Which is the largest brown algae?
The largest of the chromists are the Phaeophyta, the brown algae — the largest brown algae may reach over 30 meters in length. The rockweed shown at left, Fucus distichous, visible at low tide at the Berkeley Marina in California, is somewhat smaller. Almost all phaeophytes are marine.
Where is giant kelp found?
Giant kelp is the worlds largest species of marine algae. In the United States, it can be found along the west coast, especially around southern California where it grows in dense patches, or kelp forests.
Is algae a plant or animal?
Algae are photosynthetic creatures. They are neither plant, animal or fungi. Many algae are single celled, however some species are multicellular. Many, but not all of red and brown algae are multicellular.
Who eats algae?
The young of many aquatic animals such as frogs, fish and aquatic (water-dwelling) insects eat algae as their main source of food. Some adult fish and other creatures also eat algae. Perhaps you have seen a type of catfish that that sucks the glass sides of aquariums?
Is kelp harmful or helpful to humans?
Kelp is high in antioxidants, including carotenoids and flavonoids, which help fight against disease-causing free radicals. Antioxidant minerals, such as manganese and zinc, help combat oxidative stress and may help protect cardiovascular health and prevent cancer.
Does kelp produce oxygen?
The ocean produces oxygen through the plants (phytoplankton, kelp, and algal plankton) that live in it. These plants produce oxygen as a byproduct of photosynthesis, a process which converts carbon dioxide and sunlight into sugars the organism can use for energy.
How do humans use giant kelp?
Kelp is used to make many products: toothpastes, shampoos, salad dressings, puddings, cakes, dairy products, frozen foods, and even pharmaceuticals. Kelp farms allow growers to make use of existing aquaculture resources in their areas.
Which is not a green algae?
So, the correct option is ‘Fucus’
What is brown seaweed called?
Brown seaweed, which is known as Fucus vesiculosus or bladderwrack, is a salty sea vegetable that’s popular in many cuisines.
What is brown seaweed used for?
Brown algae are edible algae found off the coast of Japan, Korea, and China. Brown algae are used for a variety of conditions including cancer, fibromyalgia, arthritis, stress, weight loss, heart disease, high cholesterol, and many other conditions.
Who eats kelp?
Many species or kinds of fish eat kelp. Kelp is also eaten by a lot of invertebrate species. (Invertebrates are animals without backbones.) Invertebrates that eat kelp include snails and shellfish such as crabs, sea urchins and abalone.
Why does kelp grow so fast?
Like plants, however, the giant kelp harvests the sun’s energy through photosynthesis and does not feed on other organisms. This species is one of the fastest growing species in the world, and under perfect conditions, it has been known to grow up to two feet (60 cm) in a single day.
How deep can kelp grow?
Kelp forests grow along rocky coastlines in depths of about 2 m to more than 30 m (6 to 90+ ft). Kelp favors nutrient-rich, cool waters that range in temperature from 5o to 20o C (42o to 72o F). These brown algae communities live in clear water conditions through which light penetrates easily.
