Urchin populations along the California coast have exploded during the last decade, threatening kelp forests and commercial fisheries. Translocation also moves nutrients downward from light-exposed surface fronds to sporophylls (reproductive fronds) at the base of the kelp, where there is little light and thus little photosynthesis to produce food.

Kelp’s scientific name is Laminaria, it is a subgroup of Seaweeds, and it is mainly found and cultivated in the Mediterranean Sea, the Atlantic, and Pacific Oceans. The kelp often grows even longer than the distance from the bottom to the surface as it will grow in a diagonal direction due to the ocean current pushing against the kelp.

Members of the genus Nereocystis, commonly called bull kelps, are annual kelps that grow primarily in deep waters and rapid tideways and can attain lengths up to 40 metres (130 feet). Additional Information. The root-like structure helps to anchor the kelp to the ocean substrate. Giant kelp is common along the coast of the eastern Pacific Ocean, from Baja California north to southeast Alaska, and is also found in the southern oceans near South America, South Africa, Australia, and New Zealand. Where surface waters are poor in nutrients, nitrogen in the form of amino acids is translocated up the stipe through sieve elements that very much resemble the phloem of vascular plants. Saccharina latissima is a brown algae (class Phaeophyceae), of the family Laminariaceae. Choose the thickest you can find. The genus is limited in distribution because it reproduces only at temperatures below 18–20 °C (64.4–68 °F). Off the coast of Tasmania, kelp forests have been significantly affected by several factors including warming waters, shifting of the East Australian current, and invasion of long-spine sea urchins. Algin is added to ice cream before freezing to prevent ice crystallization and is also used as a suspending and emulsifying agent in other food products. and Kenyon, K.W., 1978. Sometimes known as tangles, kelps of the genus Laminaria have long flat blades and are primarily found in northern coastal regions of the Atlantic and Pacific oceans. Bull kelp is sometimes called “mermaid’s bladder,” a loose translation of this plant’s genus, Nereocystis. Until early in the 19th century, the ash of such seaweeds was an important source of potash and iodine. Many kelps produce algin, a complex carbohydrate (polysaccharide) useful in various industrial processes, including tire manufacture. The complicated body, in some ways similar in appearance to that of higher plants, has a large rootlike holdfast for attachment to the ocean floor, a stemlike stipe for the internal transport of organic material, and long branching stalks with blades that stay afloat by means of gas bladders. [17][18] Translocation of nutrients along the stipe may be as rapid as 60 cm (24 in) per hour.
