DENDROLOGY

Detailed explanation-1: -The word gymnosperms in greek means naked seeds because they do not have an outer covering or shell around their seeds. They do not produce flowers i.e they are non-flowering plants and neither do they produce fruits.

Detailed explanation-2: -Liverwort, Ferms, and Mosses are all examples of non-flowering plants because they produce spores, instead of seeds. Spores are small and unique structures present in the plants for reproduction.

Detailed explanation-3: -Flowering plants rely on pollination to disperse their seeds, meaning they need flowers to attract insects to spread the plant’s pollen about. Non-flowering plants, however-like pine trees and moss-reproduce either by scattering their seeds or spores.
