Jugalis Schrank, 1814[2] Spirogyra (common names include water silk, mermaid's tresses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus. Spirogyra species, of which there are more than 400, are ...
Oedogonium contain chloroplasts with a distinctive genome architecture. This genome is 196,547bp in length, and is the most compact among photosynthetic chlorophytes. [citation needed] It has a nonconforming quadripartite structure, with 17 group I and 4 group II introns – making it intron-rich.
The Zygnemataceae are a family [2] of filamentous or unicellular, uniseriate (unbranched) green algae. The filaments are septated and reproduction is by conjugation; Spirogyra is commonly used in schools to demonstrate this kind of reproduction. The family is notable for its diversely shaped chloroplasts, such as stellate in Zygnema, helical in ...
Chlamydomonas (/ ˌklæmɪˈdɒmənəs, - dəˈmoʊ -/ KLAM-ih-DOM-ə-nəs, -də-MOH-) is a genus of green algae consisting of about 150 species [2] of unicellular flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as "snow algae". [3] Chlamydomonas is used as a model organism for molecular ...
Conjugation in Spirogyra. Zygnematophyceae (or Conjugatophyceae) is a class of green algae in the paraphylum streptophyte algae, also referred to as Charophyta, [2] consisting of more than 4000 described species. [3] The Zygnematophyceae are the sister clade of the Embryophyta (land plants). [4][5][6]
Green algae are often classified with their embryophyte descendants in the green plant clade Viridiplantae (or Chlorobionta). Viridiplantae, together with red algae and glaucophyte algae, form the supergroup Primoplantae, also known as Archaeplastida or Plantae sensu lato. The ancestral green alga was a unicellular flagellate.

Pratella (Pers.) Gray (1821) Psalliota (Fr.) P.Kumm. (1871) Agaricus is a genus of mushroom -forming fungi containing both edible and poisonous species, with over 400 members worldwide [2][3] and possibly again as many disputed or newly-discovered species. The genus includes the common ("button") mushroom (Agaricus bisporus) and the field ...
