Although the Diversity within the Eubacteria is comparable if not more extensive than that of the Eukaryota, the Eukaryota include all of the macroorganisms (plants) that we are concerned with in this class.
The base of the Eukaryota clade is relatively resolved
BASE of the EUKARYOTA
but above that it is not very resolved and the major groups there are often called the "Crown Eukaryotes"
CROWN of the EUKARYOTA
One of the Crown lineages is the Chlorophyta & Streptophyte Lineage. This gave rise to green plants.

This leads into the LAND PLANTS
The BASAL CLADES of LAND PLANTS
The Land Plants lead to Seed Plants.
The large extant groups of Seed Plants are the Cycads, Conifers and Anthophytes.
There is much debate on the relationships of these groups to one another. The argument is primarily whether the cycads or conifers are sister to the Anthophytes. This question more than any other that we have looked at today is argued often based on the gross morphology of fossil groups because the molecular work has been far from definitive and trees generated soley on extant groups often show signs of insufficient sampling, thus fossils must be included.
Within the Anthophytes the Gnetophytes and the Magnoliophytes (Angiosperms) are sister to each other.
The whole thing can be condensed to the following cladogram.
