Of these, more than 260,000 are seed plants. Mosses, ferns, conifers, and flowering plants are all members of the plant kingdom. Some biologists also consider green algae to be plants, although many others exclude all algae from the plant kingdom and place them in Protista.

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.
