Why Are the Leaflike and Stemlike Structures?

Why are the leaflike and stemlike structures of mosses not considered true leaves and stems? ... they are both bryophytes, but they grow in different places, liverworts use sexual reproduction, mosses are asexual. How do mosses reproduce?

Why are the leaf-like structures seen in mosses not true leaves?

These are not considered true vascular tissue; they cannot use a pressure gradient to transport water against the pull of gravity. Since moss leaves lack a cuticle, they are subject to drying out. The lack of a cuticle also means that mosses can absorb water directly into their leaves in wet conditions.

Why the stem and leaf of a moss plant are not considered to be true stems and leaves?

Stem had nodes and internodes. Leaves arise from nodes and possess axillary buds. These structures are found in sporophytic plant body. Since the main plant body of bryophytes is gametophytic, the stem-like and leaf-like structures are not called stem and leaves.
