Non-flowering plants are a group of plants that do not produce flowers or seeds. Instead, they reproduce through spores or other means. Common examples include ferns, mosses, and algae. These plants can be found in various environments, often thriving in moist or shaded areas. Unlike flowering plants, non-flowering plants have different structures for reproduction. For instance, mosses reproduce using spores that are released from specialized structures called sporangia. Non-flowering plants play essential roles in ecosystems, such as providing habitat and contributing to soil health.
