Early land plants like mosses did not have vascular tissue. They must absorb their water directly from their surroundings, such as growing on rocks or trees that are moist. You find mosses in damp areas for this reason. They cannot grow in drier climates because they cannot pull water from the ground like vascular plants. Ferns are also suited to reproduce in more moist/humid climates because water must be present for their gametes (sperm and eggs) to find one another for fertilization. Seeds are adaptations by angiosperms and gymnosperms that allow for waterless fertilization. Either wind or animal pollinators help spread pollen and help the sperm reach egg cells for fertilization to occur. For that reason, these plants are better suited to survive in drier, modern climates.
