Biological Classification - The Three Divisions of Plantae

The video explains the vital role of plants on Earth, highlighting their classification into three main divisions: Bryophyta, Tracheophyta, and Spermatophyta. Bryophytes lack vascular systems and reproduce via spores, with mosses and liverworts as examples. Tracheophytes have vascular systems but also reproduce through spores, with ferns being notable members. Spermatophytes, the largest division, produce seeds and include angiosperms and gymnosperms, which are crucial for food, clothing, and wood production.
