The closest algal relatives of land plants are the Charophytes. This group of green algae shares many distinctive features with land plants such as similar metabolic pathways, sequence of DNA, RNA and proteins, and the presence of cellulosic cell walls. Additionally, in both Charophytes and land plants, the sperm structure is the same which further supports their close relationship. However, it is important to remember that Charophytes remain aquatic, and although they are close relatives, they do not represent a transitional stage to terrestrial plants.
