The correct answer is that seedless plants produce spores for reproduction. These plants, which include groups like ferns, mosses, and liverworts, rely on spores as their primary means of reproduction, distinguishing them from seeded plants. Spores are typically single cells that can develop into a new organism without the need for fertilization, and they allow these plants to thrive in various environments.

In contrast, seeded plants reproduce through seeds that contain embryos and are often part of a more complex reproductive process involving flowers and fruits. Spathiphyllum plants, a specific type of indoor plant, fall under the category of seeded plants, as they reproduce through seeds rather than spores. Perennial plants refer more to life cycles and the ability of plants to live for multiple years rather than their mode of reproduction; some perennials can indeed be seed-producing, highlighting that not all perennials reproduce by means of spores.

Thus, the emphasis on seedless plants clearly identifies their reproductive strategy through spores, making this the correct choice.
