Spore-producing plants, such as ferns, are a type of plant that reproduce by releasing spores. These spores are released from the sporangia, which are specialized structures on the underside of the leaves. The spores are then dispersed by wind or water and can travel long distances before settling in a new location. Ferns are one of the most common types of spore-producing plants, and they are found in many different habitats around the world.
