Flowering plants are known as angiosperms. Although there are plenty of plants that do not have flowers, such as mosses, ferns, algae and conifers, the majority of plants on Earth are flowering ones. That does not mean that they are what we generally think of as flowers — colourful blooms that can be presented in bouquets. Most trees and grasses, for example, are flowering plants, but their flowers may be so small that they usually go unnoticed.
No. Although most of the world’s plants are flowering plants called angiosperms (from the Greek words for “vessel” and “seed”), there are hundreds of plants that do not make flowers. Seed plants that do not have flowers such as cycads, ginkgo, and conifers are called gymnosperms. Conifers, for example, are common gymnosperms; instead of flowers, conifers have cones that produce pollen or eggs. Well-known examples are cedars, cypresses, Douglas firs, junipers, pines, redwoods, and spruces. Male cones are small and soft, and female cones are large and hard. Wind carries pollen from the male cone to the female cone. As the eggs are pollinated and seeds develop, the scales of the cone open up to release the seeds. Once the seeds take root, a new plant grows. Other plants that do not have flowers are mosses; although they sometimes look like they are blooming, the flower-like part is a little capsule full of spores at the end of a small stem.
