Sagot :

Answer:

1.The lycopods or lycophytes are one of the oldest lineages of living vascular plants. They first appeared in the Silurian period (425 million years ago), and became extremely diverse by the late Carboniferous period (323-298 million years ago) and some species grew as trees more than 100 feet tall.

2.In the given tree, gymnosperms and angiosperms have evolved most recently because they correspond to the most recent branches having the immediate common ancestor at the topmost level as compared to the immediate common ancestor of other taxon. Thus, gymnosperms and angiosperms is the right answer.

3.Liverworts

Liverworts are bryophytes, which are characterized by their lack of a vascular system.
