Marine Biology Research 5, 515-528. Kelp and sea grass (when bone meal is used) can grow into flowing water blocks, not just sources, and as a byproduct of that, the flowing water becomes a source block. Some of the kelp species are very long, and can even form kelp forests.

Commercial production of kelp harvested from its natural habitat has taken place in Japan for over a century. The species of kelp varies depending on how exposed the coast is to wave action. In 2010, researchers found that alginate, the soluble fibre substance in sea kelp, was better at preventing fat absorption than most over-the-counter slimming treatments in laboratory trials.

Alginate, a kelp-derived carbohydrate, is used to thicken products such as ice cream, jelly, salad dressing, and toothpaste, as well as an ingredient in exotic dog food and in manufactured goods. 5. Until the Leblanc process was commercialized in the early 19th century, burning of kelp in Scotland was one of the principal industrial sources of soda ash (predominantly sodium carbonate). At least until the 1840s, when there were steep falls in the price of kelp, landlords wanted to create pools of cheap or virtually free labour, supplied by families subsisting in new crofting townships. The haploid phase begins when the mature organism releases many spores, which then germinate to become male or female gametophytes. Giant Kelp have an unusual life history – a hetermorphic alternation of generations – comprising a diploid (2n) sporophyte generation (which forms the large leafy plants), which produces spores that develop into the microscopic haploid (n) gametophyte generation (comprising male and female gametophytes).
