The Charophyceae are the green algae closest to plants.
Many of the complex traits related to sexual reproduction, photosynthesis, and other plant characters, evolved first in charophyceans. Analysis of cpDNA (chloroplast DNA) shows that characteristics of plant chloroplasts evolved first in the charophycean genera Staurastrum and Zygnema.
