Question

Which of the following Phyla of plants is the most primitive? a)Phylum Coniferophyta (an example is pine) b)Phylum Pteridophyta (an example is horsetails) c) Phylum Anthophyta (an example is angiosperms) d)Phylum Bryophyta (an example is moss)

Answer 1

The most primitive plant phylum listed is the Phylum Bryophyta, including mosses, for their early appearance in evolutionary history and lack of a vascular system.

Step-by-step explanation:

The most primitive phylum of plants among the options given is Phylum Bryophyta, an example of which is moss. Bryophytes, including mosses, are considered to be some of the earliest plants to colonize land, appearing about 500 million years ago. These plants possess characteristics that are more primitive compared to other plant phyla, such as the lack of a vascular system, which is present in plants of Phylum Pteridophyta (e.g. horsetails) and the more advanced gymnosperms and angiosperms like Phylum Coniferophyta (e.g. pine) and Phylum Anthophyta (e.g. angiosperms), respectively.
