Origin and Diversity of Plants: Nonvascular Plants

The video tutorial explores the differences between green algae and plants, focusing on specialized structures like leaves, stems, and roots. It discusses the classification of plants into 12 phyla, highlighting nonvascular plants such as mosses, liverworts, and hornworts. These plants absorb water through their bodies and require moist environments for reproduction. The life cycles of mosses, liverworts, and hornworts are explained, emphasizing the alternation between sporophyte and gametophyte generations.
