Where the bottom is rocky and affords places for it to anchor, giant kelp forms extensive kelp beds with large "floating canopies". [8] When present in large numbers, giant kelp forms kelp forests that are home to many marine species that depend upon the kelp directly for food and shelter, or indirectly as a hunting ground for prey. Both the ...

In kelp this transportation network uses trumpet-shaped sieve elements (SEs). A 2015 study aimed to evaluate the efficiency of giant kelp (Macrocystis pyrifera) transport anatomy looked at 6 different laminariales species to see if they had typical vascular plant allometric relationships (if SEs had a correlation with the size of an organism).
Aquaculture of giant kelp, Macrocystis pyrifera, is the cultivation of kelp for uses such as food, dietary supplements or potash. [ 1 ] [ 2 ] Giant kelp contains iodine , potassium , other minerals vitamins and carbohydrates .
California's coast has bull and giant kelp, the world's largest marine algae. Urchins have hurt both species, though giant kelp forests have fared better.
Brown algae including kelp beds also fix a significant portion of the earth's carbon dioxide yearly through photosynthesis. [57] Additionally, they can store a great amount of carbon dioxide which can help us in the fight against climate change. [58]
This process is called photosynthesis, ... Giant kelp is a foundation species for many kelp forests. [149] The ochre starfish is a keystone predator.
Such organisms range from unicellular microalgae such as Chlorella, Prototheca and the diatoms, to multicellular macroalgae such as the giant kelp, a large brown alga which may grow up to 50 metres (160 ft) in length.
