Macrocystis pyrifera is one of the fastest-growing organisms on Earth. [23] [24]: 8 They can grow at a rate of 60 cm (2 ft) a day to reach over 45 m (150 ft) long in one growing season. [8] [25] [26] Juvenile giant kelp grow directly upon their parent female gametophyte. To establish itself, a young kelp produces one or two primary blades, and ...
The organisms require nutrient-rich water with temperatures between 6 and 14 °C (43 and 57 °F). They are known for their high growth rate—the genera Macrocystis and Nereocystis can grow as fast as half a metre a day (that is, about 20 inches a day), ultimately reaching 30 to 80 metres (100 to 260 ft).

Under ideal conditions, the alga is a fast grower and rapidly absorbs micronutrients, capable of increasing its biomass by 150% or more in a single month. In fact, it is one of the fastest growing species of Gracilaria and is one of the larger species of red algae native to the Hawaiian Islands.
The brown algae include the largest and fastest growing of seaweeds. [6] Fronds of Macrocystis may grow as much as 50 cm (20 in) per day, and the stipes can grow 6 cm (2.4 in) in a single day. [13] Growth in most brown algae occurs at the tips of structures as a result of divisions in a single apical cell or in a row of such
As the crops are rich in protein, carbohydrate, omega-3s, fatty-acids, and vitamin B12, Mr Haflidason believes growing microalgae this way, could help tackle global food insecurity.
Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. [50] [51] When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil.
Vegetation growing on Green Island on the Antarctic Peninsula, which is warming much faster than the global average. - Matt Amesbury A part of Barrientos Island that has given way to plant life.
Two-thirds of Oregon’s canopy disappeared between 2010 and 2022 due to rising ocean temperatures and an explosion of purple sea urchins, which feed voraciously on the algae.
