Question

In dicots, the primary xylem consists of a core at the ______ of the root.

Answer 1

The primary xylem in dicots forms a core at the center of the root, arranged in an X shape within the stele, surrounded by the endodermis and pericycle.

Step-by-step explanation:

In dicots, the primary xylem consists of a core at the center of the root. The vascular tissue in the root, known as the stele, features a unique arrangement where the xylem and phloem are organized alternately in an X shape. Surrounding the stele is the endodermis, a checkpoint for materials entering the root's vascular system, and the pericycle, from which lateral roots can develop.
