if you examined a cross section of a eudicot plant stem, in what order would you encounter different plant tissues from the pith
SSSSS [86.1K]

From the pith outward, if you looked at a cross-section of a eudicot plant stem, you would see Xylem, vascular, cambium, and phloem in that order. The vascular cylinder divides the ground tissue into two discrete areas and is structured in a ring in eudicot stems.

The pith refers to the area of ground tissue that is included within the vascular cylinder. In general, eudicots possess three or more of the following traits: There are 2, 4, or 5 flower parts, or multiples of 4 or 5, and leaves have netted venation (pinnate or palmate). A ring of stem vascular bundles surrounds the pith, and seeds have two seed leaves (cotyledons).

As a result, we can assert that if you cut a cross-section of a eudicot plant stem, Xylem, vascular, cambium, and phloem in that order, you will find various plant tissues from the pith outward.
