Primitive plants with leaves or fronds that unroll from the base. They reproduce with spores (a minute, single-celled, reproductive unit , capable of giving rise to a new individual without sexual fusion). The sporangium (a receptacle in which asexual spores are formed) are clustered together as little dots or sori on the bottom of the fronds (The sorus is a cluster of spore-producing receptacles on the underside of a fern frond).
