It sometimes grows on trees with a five-leafed friend. Vascular tissues are specialized for conducting food and water within the plant. All nonvascular plants are placed in one division. There are nine divisions of vascular plants based on whether they form seeds or not. Nonvascular plants are much smaller than most vascular plants.
Vascular plants live in more types of environments than nonvascular plants.
There are more than 10,000 species of moss plants. Mosses don't receive as much attention as flowering plants, ferns, or conifers because most are small and inconspicuous. They have no vascular tissue or wood, nor do they have large leaves or showy cones or flowers. This does not mean that mosses are not important. Mosses play important roles in reducing erosion along streams, water and nutrient cycling in tropical forests, and insulating the arctic permafrost.
