The class of ferns (pteridopsida) includes three living groups and several extinct groups of ferns, true or false?

The given statement is true.

Explanation:

Ferns are said to have a lineage of ancient plants back in the devonian era. These are vascular plants. The class of pteridopsida includes 3 living groups Ophioglossales, Marattiales, and leptosporangiate.

Pteridopsida also includes 2 groups of extinct ferns, Stauropteridales ferns and the oldest group of fossils Zygopteridales.

Thus, the correct answer is True.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
