Bryopsis. Bryopsis, often referred to a hair algae, [2] is a genus of marine green algae in the family Bryopsidaceae. [1] Species in the genus are macroscopic, siphonous marine green algae that are made up of units of single tubular filaments. They can form dense tufts up to 40 cm in height. [3][4] Each cell is made of up an erect thallus that ...
Polysiphonia, known as red hair algae, [1] is a genus of filamentous red algae with about 19 species on the coasts of the British Isles [2] and about 200 species worldwide, [3] including Crete in Greece, Antarctica and Greenland. [4] [5] Its members are known by a number of common names. [note 1] [4] It is in the order Ceramiales and family ...
However, there may be thousands of species of algae with this growth form, and an identification is rarely certain. [10] Green thread algae is common in newly established aquaria and is easily outcompeted by installed plants. [9] Hair algae is very similar to green thread algae. Typically, hair algae grows in a carpet of dense, short filaments.
Trichome. Fossil stellate hair (trichome) probably of an oak, in Baltic amber; image is about 1 mm wide. Trichomes (/ ˈtraɪkoʊmz, ˈtrɪkoʊmz /; from Ancient Greek τρίχωμα (tríkhōma) ' hair ') are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function.
Algae (UK: / ˈælɡiː / AL-ghee, US: / ˈældʒiː / AL-jee; [ 3 ]sg.: alga / ˈælɡə / AL-gə) are any of a large and diverse group of photosynthetic, eukaryotic organisms. The name is an informal term for a polyphyletic grouping that includes species from multiple distinct clades.
Desmarestia. Desmarestia is a genus of brown algae found worldwide. It is also called acid weed, acidweed, [2] [3] oseille de mer, sea sorrel, [4] ウルシグサ (urushi-gusa), stacheltang, mermaid's hair, landlady's wig, or gruagach. [5] However, 'sea sorrel' can also specifically refer to Desmarestia viridis. Members of this genus can be ...
The Stramenopiles, also called Heterokonts, are a clade of organisms distinguished by the presence of stiff tripartite external hairs. In most species, the hairs are attached to flagella, in some they are attached to other areas of the cellular surface, and in some they have been secondarily lost (in which case relatedness to stramenopile ancestors is evident from other shared cytological ...
Marimo. Marimo[a] (also known as Cladophora ball, moss ball, moss ball pet, or lake ball) is a rare growth form of Aegagropila linnaei (a species of filamentous green algae) in which the algae grow into large green balls with a velvety appearance. The species can be found in a number of lakes and rivers in Japan and Northern Europe. [1]
