While examining the transverse section of a plant part under a microscope, a student observes radial vascular bundles with exactly four xylem patches (tetrarch condition). Based on this observation, which of the following correctly describes the nature of the pith in this plant part?

Step-by-step solution

Identify the plant part based on the vascular bundle arrangement. Radial vascular bundles are a characteristic feature of roots. Determine the class of the root. The presence of four xylem patches (tetrarch condition) indicates a dicot root, as dicot roots typically have two to four (diarch to hexarch) xylem patches. In contrast, monocot roots usually have more than six (polyarch) xylem bundles. Recall the anatomical features of a dicot root. According to NCERT, the pith in a dicot root is small or inconspicuous.
