DENDROLOGY

Detailed explanation-1: -It includes both angiosperms (flowering plants) and gymnosperms (non-flowering plants). They have evident sex organs or phanerogamae . In gymnosperms, the seeds are naked, whereas in angiosperms, it is enclosed.

Detailed explanation-2: -Flowering plants have flowers, and nonflowering plants do not.

Detailed explanation-3: -Non-flowering plants include mosses, liverworts, hornworts, lycophytes and ferns and reproduce by spores. Some non-flowering plants, called gymnosperms or conifers, still produce seeds.

Detailed explanation-4: -Non-flowering plants mostly fall into one of these groups: ferns, liverworts, mosses, hornworts, whisk ferns, club mosses, horsetails, conifers, cycads, and ginkgo. We can group those together based on how they grow.

Detailed explanation-5: -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.
