Exam (elaborations) BIOLOGY 1301 Lab #7 - Seedless Vascular Plants Lab #7 Seedless Vascular Plants Introduction In today’s lab, we will study seedless vascular plants. This plant group evolved by the late Devonian period and was the prominent group during the Carboniferous period of the Paleozoic era. They formed the first forests about 385 million years ago. These forests are the main source of fossil fuels we use today. Critical innovations that lead to the success of seedless vascular plan...
