Plants as biological objects are classified with the aim of being easy to study. Kingdom plantae has four divisions that represent plant members, namely:
Division Thallophyta (thallus plants), plants whose body structure is still a thallus (roots, stems and leaves false or unclear). Examples of plants including thallophyta are algae (algae).
Algae (algae)
Division Bryophyta (mosses), group of mosses and classified as kormophyta, that is, the body structure is kormus (roots, stems and true leaves). Examples are liverworts (hepaticae), leaf mosses (musci) and hornworts.
Bryophyta
Division of Pteridophyta (ferns), group of ferns and also classified as kormophyta, that is, the body structure is kormus (roots, stems and true leaves). Ferns are divided into four subdivisions, namely Psilophyta (Psilotum sp.), Lycophyta (Selaginella sp.), Spenophyta and pterophyta (Marsilea creanata, Asplenium nidus).
Pterydophyta
Division Spermatophyta (seed plants), a group of plants that have seeds as a means of generative reproduction. Spermatophyta is divided into two subdivisions, namely Gymnosperms (plants with open seeds) and Angiosperms (plants with closed seeds). Gymnosperms consist of four families, namely cycadinae (Cycas tumpii, hajj fern), gnetinae (Gentum gnemon, melinjo), coniferinae (Agathis alba, damar) and ginkgoinae (Gingkgo biloba). Angiosperms consist of two classes, namely the monocotyledonae class (one-piece plants); for example rice, banana, bamboo and class dicotyledonae (plants with two pieces); for example rubber trees, mango and guava.
