Question
In what era did the first land plants appear?
Solution
The first land plants appeared during the Ordovician period, which is part of the Paleozoic era. This period occurred around 470 million years ago. Here are the steps to understand this:
-
The history of Earth is divided into several eons, each of which is further divided into eras, periods, epochs, and ages.
-
The first land plants appeared during the Paleozoic era, which is the era that occurred after the Precambrian eon and before the Mesozoic era.
-
Within the Paleozoic era, there are six periods: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian.
-
The first land plants appeared during the Ordovician period, which is the second period of the Paleozoic era.
-
The Ordovician period occurred around 470 million years ago. During this time, the first simple plants began to colonize the land, evolving from green algae in the ocean.
-
These early plants were likely similar to liverworts, a type of non-vascular plant that is still around today. They would have been very simple, lacking roots, leaves, or flowers.
-
Over time, these simple plants evolved into more complex forms, leading to the diverse array of plant life we see on Earth today.

The first known forests on Earth arose in the Middle Devonian (approximately 390 million years ago), with the evolution of cladoxylopsid plants like Calamophyton.[30] Appeared in the Late Devonian, Archaeopteris was both tree-like and fern-like plant, growing to 20 metres (66 ft) in height or more.[31] It quickly spread throughout the world, from the equator to subpolar latitudes.[31] It is the first species known to cast shade due to its fronds and by forming soil from its roots. Archaeopteris was deciduous, dropping its fronds onto the forest floor, the shade, soil, and forest duff from the dropped fronds creating the early forest.[31] The shed organic matter altered the freshwater environment, slowing its flow and providing food. This promoted freshwater fish.[31]
