Charophyceae is a class (biology) of charophyte green algae. Some botanists include Charophyceae and chlorophyte green algae in the plant kingdom. Charophyceae are a class within the Streptophyta. [2 ] [3 ] [4 ] Current consensus treats Charophyceae as a class under division Charophyta, with Chlorophyta remaining a distinct division. [5 ] [6 ]
Many of the complex traits related to sexual reproduction,
photosynthesis, and other defining characteristics of plants evolved first in Streptophytes; analysis of cpDNA ( chloroplast DNA), for instance, reveals that many characteristics of plant chloroplasts evolved first in the Streptophyte genera and Staurastrum . Zygnema [2 ] [7 ]
