The History of Land Plants🌱Part 1Plants first arrived on land around 450 million years ago during the Ordovician period. About 50 million years before animals emerged on landThese plants were very small because they didn’t have the systems to pump water through their bodies, so they needed to stay low to the ground. This is also before the evolution of seeds, so the plants depended upon the presence of water to spread their gametes for reproduction. Examples of these kinds of plants that you ca

The Story of Land Plants🌱Part 2 As land plants became more diverse and populated, the plants needed to adapt to gain an advantage for light and water Plants evolved vascular systems in the late Ordovician period (420 million years ago) This allowed the plants to begin to grow up off the ground and to carry the water up to their cells to facilitate their functions including cellular respiration. To support the vertical growth and increased demand for water, plants began to develop roots A plant

While the Cambrian critters are a hard show to follow, fossil evidence tells us that life on earth diversified even more than during the cambrian explosion! Unfortunately, it all came crashing down, as the end of Ordovician is marked by one of the first of the 5 big mass extinctions. The event was even more deadly than the one that killed non-avian dinosa
