Which of the following responses is the correct order of tissues from the center to the periphery (outside)of a two-year-old dicot stem cross section?

Question

Quizplus · Accepted Answer

In a two-year-old dicot stem, the correct order from the center to the periphery is primary xylem, secondary xylem, vascular cambium, secondary phloem, and secondary xylem. This sequence reflects the typical arrangement of tissues in a dicot stem, where the primary xylem is located at the center, followed by the secondary xylem which is produced after the primary growth phase. The vascular cambium, a layer of meristematic tissue, is responsible for the production of secondary xylem (inwards) and secondary phloem (outwards). The secondary phloem is then located towards the periphery. The repetition of "secondary xylem" in the options is a mistake; the correct sequence should not repeat tissue types.
