Members of the kingdom Plantae are characterized by containing the green pigment chlorophyll which enables them to use light as their main source of energy. They include liverworts, hornworts, mosses, clubmosses, quillworts, horsetails, ferns, cycads, gingkos, conifers and the host of flowering plants and grasses that surround us.
