They do not have roots, but have long dead cells capable of water absorbency via apoplastic transport, these cells are called rhizoid cells. Their sporophyte is reduced to sporogon, which is simply a sporangium with setamosses: stalk of the sporogon (see) (stalk), and is usually parasitic. Gametophyte of bryophytes starts its development from a protonema, thread of cells.

In this latter type of reproduction, the gemmae—small, intact, complete pieces of plant that are produced in a cup on the surface of the thallus (shown in Figure 25.11 and Figure 25.12)—are splashed out of the cup by raindrops.

The first bryophytes (liverworts) most likely appeared in the Ordovician period, about 450 million years ago. Because of the lack of lignin and other resistant structures, the likelihood of bryophytes forming fossils is rather small. Some spores protected by sporopollenin have survived and are attributed to early bryophytes.

Lacking vascular tissue, these early plants generally have a prostrate form and grow closely appressed to the substrate. They lack true roots but have anchoring cells called rhizoids that extend from the gametophyte. Bryophytes have a gametophyte dominant life cycle and the sporophytes grow from the megagametophyte.

These non-vascular plants, totaling around 23,000 species, thrive in moist environments. Mosses exhibit erect structures with spirally arranged leaves, while liverworts have flat bodies. Their life cycle features alternation of generations, encompassing gametophyte for sexual reproduction and sporophyte for spore dispersal.

When the sporophyte emerges from the archegonium, it tears off the venter and creates a sort of cap on the sporangium, called a calyptra. This long section shows the developing sporangia (surrounding the grey areas), the operculum (covering the tip of the capsule), and the peristome teeth just below. While looking through the dissecting scope and focused on the peristome, remove the lid of the petri dish.
