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]
Red algae, or Rhodophyta (/ r oʊ ... If the kingdom Plantae is defined as the Archaeplastida, then red algae will be part of that group. If Plantae are defined more ...
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]
The glaucophytes are of interest to biologists studying the evolution of chloroplasts as they may be similar to the original algal type that led to the red algae and green plants, i.e. glaucophytes may be basal Archaeplastida. [1] [7] [4] Unlike red and green algae, glaucophytes only have asexual reproduction. [8]

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.
Florideophyceae is a class of exclusively multicellular red algae. [3] [4] They were once thought to be the only algae to bear pit connections, [5] but these have since been found in the filamentous stage of the Bangiaceae. [6] They were also thought only to exhibit apical growth, but there are genera known to grow by intercalary growth. [6]
