It is at the end of these stems that the reproductive cells are produced. This usually happens in early springtime. The male reproductive cells and the eggs are not always produced on the same stem. In the case of some mosses these cells are produced by different plants;

The Spore-producing Plants ... The spores are microscopic and so they are easily carried by the wind. ... The sperms are produced on one part of the prothallus and they swim in a film of water towards the eggs. The fertilized egg cell will grow into a young fern. Once the fern plant has established itself the prothallus dies.

The plant life cycle has mitosis occurring in spores, produced by meiosis, that germinate into the gametophyte phase. ... Plants that produce separate male and female gametophytes have those gametophytes germinate from (or within in the case of the more advanced plants) spores of different sizes (heterospores;

Spores are produced by the lower plants, most fungi, some bacteria, and certain protozoa. They are generally light and easily dispersed by wind movements. ... Plant spores are haploid (having a single set of chromosomes in each cell) and are produced by the sporophyte, following meiosis; see alternation of generations.
