Solution
Plant Kingdom – PlantaeLevel of classification is based on the following three criteria:
1.Plant body– whether the body has well-differentiated structures or not.2.Vascular system-whether the plant has vascular system for transportation of substances or not.
3.Seed formation– whether the plant bears flowers and seeds or not; if it does, then whether it is enclosed within fruits or not.
The two subgroups are:-Cryptogams- reproduction through spores and no seed formation. They include subgroups Thallophyta, Bryophyta and Pteridophyta
Phanerogams-they have specialized reproductive organs and they produce seeds. Gymnosperms and Angiosperms belong to this group.
