Are You Overlooking the Microscopic Forest at Your Feet? The Fascinating World of Liverworts<\/h3>\n

Do you ever pay attention to the green ‘moss’ spreading across the roadsides and forgotten corners of schoolyards you walk past every day? Bryophytes\u2014the group that includes mosses and liverworts\u2014are actually like living fossils, carrying the ancient history of when plants first moved from the sea onto land.<\/p>\n

When teaching plant reproduction in science class, these non-vascular plants become a profoundly interesting subject for observation. This time, we used the common liverwort (*Marchantia polymorpha*) found on our campus to observe the dramatic structural differences between the male and female plants, and the ‘spores’ that guarantee the next generation. The microscopic world seen through a microscope is guaranteed to amaze your students!<\/p>\n

Let’s Collect Liverworts! The Reason They Love Damp Places<\/h3>\n

Liverworts thrive in moist areas and are often found growing naturally near water features or on shaded, damp ground around the school. Why the preference for wet places? This is because bryophytes haven’t yet developed vascular bundles (the internal ‘plumbing’ for water transport), so they must absorb water directly through their body surfaces. Additionally, as we’ll explain shortly, water is absolutely essential for fertilization.<\/p>\n

We carefully collected our specimens using a small trowel. When collecting, make sure to take the entire plant, including the root-like structures (rhizoids), and wrap them in a damp paper towel or paper to keep them from drying out.<\/p>\n

A Clear Difference! The Distinct Shapes of Male and Female Plants<\/h3>\n

Take a good look at the liverwort you collected. It turns out that, just like humans, liverworts have distinct ‘male’ and ‘female’ plants. And their shapes are surprisingly different from each other.<\/p>\n
