The Zygnematophyceae, formerly known as the Conjugatophyceae, generally possess two fairly elaborate chloroplasts in each cell, rather than many discoid ones. They reproduce asexually by the development of a septum between the two cell-halves or semi-cells (in unicellular forms, each daughter-cell develops the other semi-cell afresh) and sexually by conjugation, or the fusion of the entire ...
Charophyceae is a class of charophyte green algae. AlgaeBase places it in division Charophyta. [1] Extant (living) species are placed in a single order Charales, [2] commonly known as "stoneworts" and "brittleworts".
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).
This category contains valid Charophyta species names, i.e. species of Streptophyta with the exclusion of land plants. Alternate names (i.e. junior synonyms) are not included here. Italicized entries are articles about species in monotypic genera; these are redirected to their appropriate genus article.

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.

Charales is an order of freshwater green algae in the division Charophyta, class Charophyceae, commonly known as stoneworts. Depending on the treatment of the genus Nitellopsis , living (extant) species are placed into either one family ( Characeae ) or two (Characeae and Feistiellaceae ).
