1) The caulinar apical meristem is found at the insertion points of the leaves to the stem.

2) The internode is the segment of the stem found between two consecutive leaves, and it does not show lateral organs.

3) Some plant species may have a stem showing primary and secondary growth at the same time.

4) The growing in length of stems is a consequence of the apical and intercalary meristems.

5) Stems do not have stomata.

6) In the primary stems, the cortex is an inner layer.

7) The vascular bundle organization in primary stems is a feature that allows us to differentiate between monocots and dicots.

8) The presence of vascular cambium indicates a stem with secondary growth.

9) Stem growth rings are produced by the periderm activity.

10) The interfascicular tissue may differentiate into vascular tissue.

11) A typical structure of a primary stem is the periderm.

12) The medullary region is larger in the thicker stems.

13) The dotted lines delimit the primary phloem.

14) The dotted line encloses the primary xylem.

15) The dotted lines indicate the secondary xylem.

16) The dotted lines delimit the primary phloem.
