The clubmosses and their relatives are the most ancient group of vascular plants — plants with specialized tissue called xylem that transports water and nutrients throughout the plant. The only plant ...

This primitive, non-vascular plant has more in common with mosses and ferns than the more familiar seed-bearing plants. Liverworts can be divided into two very distinct forms: leafy and thallose.

They were non-vascular plants, like mosses and liverworts, that didn’t have deep roots. About 35 million years later, ice sheets briefly covered much of the planet and a mass extinction ensued.

Non-vascular plants, such as mosses, hornworts and liverworts, probably evolved during the Ordovician period, around 450 million years ago. They are older than vascular plants, ...

Archaeobotanists at the University of Glasgow in Scotland, UK, have identified more than 75 species of bryophytes (non-vascular plants that include mosses and liverworts) frozen alongside Ötzi ...

The Late Ordovician period, ending 444 million years ago, was marked by the onset of glaciations. The expansion of non-vascular land plants accelerated chemical weathering and may have drawn down ...

Moss is the oldest terrestrial plant on Earth. It is also the only non-vascular plant on Earth, which means it does not have roots and survives by absorbing the moisture in the atmosphere through ...

Vascular plants make up most plants on Earth and include trees, shrubs, herbs, ferns and grasses. They have a circulatory system, unlike non-vascular plants such as mosses and liverworts.
