Since algae is a broad term including organisms of widely varying sizes, growth rates, ... higher concentrations cause increased growth of algae and plants. Algae ...
Many other algal species (Heterosigma akashiwo, Chattonella marina, and Chattonella antiqua) have also been shown to produce the highest amounts of ROS during the exponential phase of growth. [ 50 ] [ 52 ] Oda et al. [ 16 ] suggest this is due to actively growing cells having higher photosynthesis and metabolic rates.
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
Tip growth is an extreme form of polarised growth of living cells that results in an elongated cylindrical cell morphology with a rounded tip at which the growth activity takes place. Tip growth occurs in algae (e.g., Acetabularia acetabulum ), fungi ( hyphae ) and plants (e.g. root hairs and pollen tubes ).
Algae (UK: / ˈ æ l ɡ iː / AL-ghee, US: / ˈ æ l dʒ iː / AL-jee; [3] sg.: alga / ˈ æ l ɡ ə / AL-gə) is an informal term for any organisms of a large and diverse group of photosynthetic eukaryotes, which include species from multiple distinct clades.
Maerl (also rhodolith) is a collective name for non-geniculate coralline red algae with a certain growth habit. [1] Maerl grows at a rate of c. 1 mm per year. [2] It accumulates as unattached particles and forms extensive beds in suitable sublittoral sites. [3] The term maerl originally refers to the branched growth form of Lemoine (1910) [4 ...
The rate of glacier melt depends on the surface albedo. Recent research has shown the growth of snow and glacier ice algae darkens local surface conditions, decreasing the albedo and thus increases the melt rate on these surfaces. [46] [45] [47] Melting glaciers and ice sheets have been directly linked to increase in sea level rise. [48]
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).
