Explanation:

Seedless plants, such as ferns, mosses, and liverworts, reproduce via spores. Spores are small, single - celled reproductive units. Sphentopytes are a group of plants (e.g., horsetails), microphylls are small leaves (in some lycophytes), and xylem is a vascular tissue for water transport.

spores
