What term refers to segmented worms?

The term that refers to segmented worms is "Annelida." This classification includes various species of worms characterized by their segmented bodies, which is a key feature that distinguishes them from other types of worms. Annelids have a complex body structure that allows for specialization of different segments, contributing to their adaptability in various environments. This group encompasses familiar organisms like earthworms and leeches, which play vital roles in ecosystems, such as improving soil health and recycling nutrients.

The other terms provided refer to different biological classifications: Gekophyta is related to certain types of plants, Angiosperms refers to flowering plants that produce seeds enclosed within a fruit, and Mollusca encompasses a diverse group of invertebrates like snails, clams, and octopuses, which do not exhibit segmentation in the same way annelids do. Therefore, Annelida is the appropriate term for segmented worms.
