What organisms are considered the ancestors of terrestrial plants?

In the process of mountain building at the end of the Silurian 405-440 million years ago, algae similar to modern charovy algae emerge on land and occupy the littoral and supralittoral zones, which became possible due to the activity of bacteria that formed the soil substrate on the land surface. This is how the first higher plants appear – rhinophytes. It can be argued that in terms of the main similar features of the structure and appearance, the psilotes are very similar, if not to the most ancient, then to very ancient and primitive plant forms.
