Mosses and liverwortsThe earliest land plants appeared around 470 million years ago during the Ordovician period123. These were non-vascular plants, such as mosses and liverworts, which lacked deep roots and could not survive without contact with water4. Later, vascular land plants with more complex structures evolved, including those with vascular tissues5.Learn more:âś•This summary was generated using AI based on multiple online sources.

Individual trilete spores resembling those of modern cryptogamic plants and vascular plants first appeared in the fossil record from the Late Ordovician. These plants probably...
en.wikipedia.org/wiki/Timeline_of_plant_evolutionEvidence of the earliest land plants occurs at about 470 million years ago, in lower middle Ordovician rocks from Saudi Arabia and Gondwana in the form of spores known as cryptospores. These spores have walls made of sporopollenin, an extremely decay-resistant material that means they are well-preserved by the fossil record.en.wikipedia.org/wiki/Evolutionary_history_of_plantsThe first land plants appeared around 470 million years ago, during the Ordovician period, when life was diversifying rapidly. 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.www.newscientist.com/article/dn21417-first-land-pl…Non-vascular plants, which include mosses and liverworts, were the first-ever land plants. They do not have much of an internal support system, but have slightly simpler material for the same tasks. They cannot survive without contact with a body of water, and will soon dry out and die if there is no dampness around them.eartharchives.org/articles/the-evolution-of-plants-p…Now, fossils have been found that show vascular land plants existed in the mid to late Ordovician period, as early as 450 million years ago, the scientists say. It’s widely believed that the earliest land plants were mosslike and, in lieu of vascular tissues, absorbed water and minerals and then passed them among unspecialized cells.www.sciencenews.org/article/earlier-appearance-fir…The first plants - Earth History

Timeline of plant evolution - Wikipedia
In the strictest sense, the name plant refers to those land plants that form the clade Embryophyta, comprising the bryophytes and vascular plants. However, the clade Viridiplantae or green plants includes some other groups of photosynthetic eukaryotes, including green algae. It is widely believed that land plants evolved from a group of charophytes, most likely simple single-celled terrestrial algae similar to extant Klebsormidiophyceae.

Evolutionary history of plants - Wikipedia
Land plants evolved from a group of freshwater green algae, perhaps as early as 850 mya, but algae-like plants might have evolved as early as 1 billion years ago. The closest living relatives of land plants are the charophytes, specifically Charales; if modern Charales are similar to the distant ancestors they share with land plants, this means that the land plants evolved from a branched, fila…
