These complex structures are produced by the sporophyte plants. As they evolved over the ensuing millenia, they developed adaptations that antyophyta them ever more successful in the competition for a place in the sun. Individual plants, excepting some algae, do not have the ability to move from place to place as many Protista and animals do.

Some, such as pitcher plants, are even insectivorous. Identify the central pistil female part which consists of the ovary at the base, a long style extending out from it and a broad tip called the stigma that catches pollen. Anhophyta example, the Venus fly trap has leaves covered by little hairs.
