Yes it is, and Liverworts were the first land plants.
Cambrian period
Since all known land plants have a vascular system, it is likely that the first land plant also had a vascular system. Researchers believe that there were two types of plants that may have been the first land plants. These are called rhynia and zosterophyllum.
The ancestors of land plants, green algae, lack the structural support to stand erect in air.

a long time ago
The first plants with spores, which indicates that they were land plants, appeared in the Middle Ordovician period, about 470 million years ago. First records of tetrapods, or land animals, show up in the fossil record around 370 million years ago.
Algae are one of the oldest lineages, from before plants went onto land. Bryophytes are of the first lineage to live on land.
Cambrian period
Nonvascular plants
Cooksonia was the most successful land conqueror and was the first of an entirely new kind of plants that was no longer an alga or bryophyte.
