Answer:
Pteridophyta examples are : 1. Ferns, 2. Horsetails 3. Club mosses
Explanation:
Pteridophytes are vascular plants and have leaves (known as fronds), roots, and sometimes true stems, and tree ferns have full trunks. Examples include ferns, horsetails, and club mosses. Fronds in the largest species of ferns can reach some six metres in length!
Many ferns from tropical rain forests are epiphytes, which means they only grow on other plant species; their water comes from the damp air or from rainfall running down branches and tree trunks. There are also some purely aquatic ferns such as water fern or water velvet (Salvinia molesta) and mosquito ferns (Azolla species).
