Mosses are similar to ferns in that they produce spores.
The spores are both male and female. The male spores have cells that travel through small tubes to join with female spores to produce new moss. Mosses lack the roots and stems that other plants have. They fix themselves to objects in cool moist locations where it is easier for them to get the water and nutrients they need for survival. Mosses often grow so close together that they form pads, or cushions.
