The trunk of a tree is its root stem leaf flower

Stem

The trunk of a tree is the stem part of the tree. It is the main wooden axis of the tree. It is important for identifying a particular tree species. The composition of the tree trunk varies from the bottom to the top. Trunks occur in both true woody plants and in the non woody plants. The thickening of the tree trunk is because of the formation of the secondary growth.

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.
