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]
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 ...
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.
Batrachospermaceae [2] is a family of fresh water red algae (Rhodophyta). Genera within the Batrachospermaceae generally have a "Lemanea-type" life history with carpospores germinating to produce chantransia. [3] Sporophyte phase with meiosis occurs in an apical cell to produce the gametophyte stage. [3]
Light microscopy of Polysiphonia showing a tetraspore within a tetrasporophyte cell. A=Tetraspore, B=Tetrasporophyte cell.Scale bar = 0.02 mm. Tetraspores are red algae spores produced by the tetrasporophytic phase in the life history of algae in the Rhodophyta as a result of meiosis. [1]
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 ...
It's Labor Day weekend, which is a sign that summer is nearing the end.So, if you're headed to a beach for one last dip, don't forget to check the latest water quality reports before you head out.
The Archaeplastida (or kingdom Plantae sensu lato "in a broad sense"; pronounced / ɑːr k ɪ ˈ p l æ s t ɪ d ə /) are a major group of eukaryotes, comprising the photoautotrophic red algae (Rhodophyta), green algae, land plants, and the minor group glaucophytes. [6]
