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 ...
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]
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.
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 ...
Laurencia is a small to medium-sized red algae which may appear to be iridescent with thalli reaching up to 40 cm. Thalli can be branching, which can either be bilateral or spread in all directions. Its appendages can be rhizoidal or discoidal in appearance on stoloniferous holdfasts.
Asparagopsis taxiformis (red sea plume or limu kohu), formerly A. sanfordiana, [1] is a species of red algae, with cosmopolitan distribution in tropical to warm temperate waters. [2] Researchers have demonstrated that feeding ruminants a diet containing 0.2% A. taxiformis seaweed reduced their methane emissions by nearly 99 percent.
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]
