Plants can be divided into two broad categories based on their means of reproduction: flowering plants and non-flowering plants. Non-flowering plants can be defined as those group of plants that do not produce flowers for reproduction. They are simpler in organization as compared to the flowering plants. Some still refer algae and fungi in the group of non-flowering plants. However, these are not true plants, as they lack true roots and leaves. Non-flowering plants, or gymnosperms, produce seeds and have a multitude of uses, including for evergreen landscaping, lumber, paper, food, fuel and medicine. There are more than 700 types of non-flowering plants.
Non flowering plants are simpler than the flowering plants. Non flowering plants also have a higher level of adaptability to the environment. This is the main reason why they have survived for so long through all the changes on earth. Non flowering plants such as mosses, ferns, fungi and algae reproduce with the help of spores since they do not have flowers nor do they make seeds. Instead, nonflowering plants produce spores that resemble seeds. This is also called asexual reproduction. Spores are reproductive cells of nonflowering plants and contain the genetic material of the plant inside a hard casing. New plants grow from these spores under the right environmental conditions.
