The sub-kingdom Phanerogamae consists of plants that bear seeds with evident reproductive organs called as “Flowers”. They are the most advanced plants, with well-developed roots, leaves, stems, and flowers.
The sub-kingdom Phanerogamae is divided into 2 groups – Angiosperms and Gymnosperms, based on the presence or absence of fruits, or the presence of naked ovules or protected ovules.
