there are two main types of plants: flowering plants and nonflowering plants.

nonflowering plants include coniferous trees, mosses, liver-worts, algae and fungi. you cannot see many nonflowering plants around you.

most plants do not grow from seeds. they grow from spores. spores are very, very small. some spores are so small and light that they can float in the air. we may say that spores are quite similar to seeds. when these spores fall on wet and shady② places, they usually grow into new plants.
