Read the passage to answer the question. have you had the chance to watch a tree grow over a span of several years? did you notice that the tree grew thicker and taller? deep in the roots of the tree and high in the growing shoots are meristem cells. each year, the meristem cells the tree continue to grow. question 2 as a tree ages, it needs to keep making more xylem and phloem cells to carry water and food. which statement explains how this occurs?
meristem cells divide and some of the new cells differentiate into xylem and phloem.
xylem and phloem from one part of the plant are transferred to another part.
cell division is not necessary for a plant to create new xylem and phloem cells.
the existing xylem and phloem divide to make more xylem and phloem.

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.
