It is believed modern plants, land plants or higher plants, evolved from marine algae, or to put it simply: seaweed. This is theory and has not been conclusively proven. The algae would become a primitive plant such as a bryophyte (mosses and nonseed plants), and then from there a "higher plant," such as angiosperms.

Most of them come from seeds produced by flowers. Some can come from plant roots. Some come from nuts.
