Some algae are edible. Nori, from the red alga, porphyra, is a favorite in Japanese cuisine. Caulpera, a green alga commonly called arosep, is prepared as salad. A number of important products are derived from the cell walls of algae. Agar,derived from red algae, is one product used in making processed cheese, pudding, mayonnaise, jelly, and ice cream. It is also used in making gel capsules for some medicines. It is an ingridient of lotion, ointment, shoe polish, and shaving cream. It is also used as an important growth medium for bacteria in laboratory research work. Another product derived from red algae is carrageenan, which is similar to agar. Carrageenan is used in the production of milk shake, ice cream, sherbet, instant pudding, and creamed soup. It is also a constituent of toothpaste and lotion. Derived from brown algae are thickeners, which are used in making ice cream, shaving cream, rubber, paint, and dental impression mold.Some brown algae are used as fertilizers, and as cattle feed supplements.

Where does coral get its color from?
Zooxanthellae, are microscopic, single-celled algae that live and grow within the tissue of hard coral polyps. Several million zooxanthellae live in just one square inch of coral. Coral polyps and their skeletons are actually clear or white and it is pigment in the zooxanthellae that gives coral more than 90% of its colorful hues.
What plant live in coral reefs?
Algae and seagrasses are the main types of plants found in a coral reef environment. They are primary producers and provide the basic food supply for the entire reef ecosystem. Algae range in size from simple unicellular plants such as zooxanthellae, found in the coral polyp to multicellular branching forms which are commonly called sea weeds. Pigments in the algae give each type its characteristic color, for example red algae, brown algae and green algae. Two main types of multicellular algae found on reefs are coralline algae and calcareous algae. Not only are these algae food for some coral reef animals, but they also contribute to the making of the limestone framework of the reef. Coralline algae are made up of masses of very fine thread-like filaments, that spread out in thin layers over the reef rock surface. These filaments produce calcium carbonate thus giving the algae an appearance more like a rock than a plant. The encrusting filaments trap sediments of sand, as well as cement the particles of sand together. Thus coralline algae help to stabilize the coral reef structure. Calcareous algae do not encrust like coralline algae, but grow erect. They too produce calcium carbonate (limestone). When these algae die, the limestone remains produce sand. One type of calcareous algae known as Halimeda produces about fifty percent of the sand found on some of our beaches in the Caribbean. Below are diagrams of some reef algae. HALIMEDA PENCILLUS CORALLINA Seagrass beds are often found in areas where coral reefs grow. Turtle grass, manatee grass and shoal grass are three types of seagrasses commonly found in the Caribbean Sea. Unlike algae, seagrasses are true flowering plants. Seagrasses serve as a habitat and shelter for reef animals such as the young or juveniles of conch and lobsters. These plants also provide food for many herbivorous reef fish. The leaves of seagrass are also a habitat for very tiny organisms.
What is the relationship between the coral polyps and the algae that live in them?
Coral and algae (specifically the algae called zooxanthellae) have an intimate symbiotic relationship. The algae live inside the coral, and provide it with sugars and other photosynthesis byproducts. The coral provides the algae with nutrients for photosynthesis and a safe place to live and reproduce.
How does algae benefit the corals?
Many corals, specifically hermatypic corals, contain symbiotic algae that provide the coral with sugar from photosynthesis. Algae also feed zooplankton, which corals feed on. Basically, algae provide corals with food, indirectly.
What adaptations did algae have to live in the coral reef?
It had to start photosynthesis.
Is it bad when coral loses the algae?
Yes, because algae provide coral reef with nutrients
How does algae help coral?
The algae helps the coral by producing oxygen and other nutrients that are required by the coral. The coral produces carbon dioxide for the algae as well as other substances the algae requires.
Why do corral live in shallow water?
Coral live in shallow waters because they have a special relationship with algae. The algae live in shallow waters and carry on photosynthesis. Algae grow inside coral. They help the coral grow and build a skeleton.
How does algae benefit from living insdie coral polyps?
When a coral polyp is formed it takes in the algae and the algae carries onto photosynthesis inside the coral. The algae later helps the coral change calcium salts in seawater into a hard calcium carbonate structure that makes up a coral reef. Without the algae helping to create calcium carbonate, a coral reef wouldn't have it's nice structure.
Why can't coral reefs survive more than 40 meters below the ocean's surface?
Living coral must remain relatively close to the surface of the water so that the symbiotic algae can have access to sunshine. The algae requires sunshine in order to complete photosynthesis which provides oxygen to the coral.
What type of algae forms coral reef?
Microscopic Algae live in coral reefs
Explain the symbiotic relationship between coral polyp and algae?
It's a mutualistic symbiosis, and occours in corals, jellyfishes and other polyps.* The symbionts, called zoochlorellae if they are green algae or zooxanthellae if they are protozoans, with photosynthesis produce: # Sugars, wich can feed the host up to 90% of its energy request. # Oxygen. * The cnidarian (coral, jellyfish or hydropolyp) gives to zoochlorellae (or to zooxanthellae) his products of waste: # CO2 (which decreasing helps hermatypic corals forming their skeletons) # Minerals. # Nitrogen. In order to perform photosynthesis, zoochlorellae and zooxanthellae need light, so they can stay only in shallow waters.
How do the tiny coral reef get their food?
Coral reefs get their food from one-celled algae organisms called zooxanthellae. They give the coral by-products of photosynthesis. Also, coral have little carnivorous organisms living in them that kill and eat things with little stinging tentacles.
Is algae part of the coral reef ecosystem?
Algae plays a vital role in the coral reef ecosystem. Firstly, algae feeds the zooplankton that forms part of the base of the foodchain of the coral reefs. Secondly, algae live inside the actual coral, and are responsible for providing the coral with a huge amount of energy.
