A carpospore is a diploid spore produced by red algae. After fertilization, the alga's carpogonium subdivides into carpospores, and generally the largest type of spore (larger than bispores, which are larger again than tetraspores). [1] The wall of the carposporangium then breaks down, releasing the spores into the environment. [2]
Laurencia belongs to the family Rhodomelaceae which is considered to be one of the largest marine red algae family, estimated to have 125 genera and 700 species all over the world. In Laurenciae, a tribe consisting of eight genera, have a taxonomic group called " Laurencia complex " or Laurencia sensu lato which includes six of eight genera ...
Red algae, like Gracilaria, Gelidium, Euchema, Porphyra, Acanthophora, and Palmaria are primarily known for their industrial use for phycocolloids (agar, algin, furcellaran and carrageenan) as thickening agent, textiles, food, anticoagulants, water-binding agents, etc. [87] Dulse (Palmaria palmata) is one of the most consumed red algae and is a ...
Batrachospermum is a genus of red algae from the family Batrachospermaceae.Due to its complex biological life cycle, descriptions of the taxon typically focus on gametophytes, while sporophytes, i.e., carposporophytes, are filamentous structures growing on the gametophyte, on which they depend.
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. Oedogonium in particular may be referred to as hair algae. Hair algae may be caused by too much light in the aquaria. [11]
The marine red alga Porphyra has been cultivated extensively in many Asian countries as an edible seaweed used to wrap the rice and fish that compose the Japanese food sushi and the Korean food gimbap. In Japan, the annual production of Porphyra species is valued at 100 billion yen (US$1 billion). [11]
