In stem, the proto-xylem lies towards the _____________ and the meta-xylem lies towards the ____________

• A. center; periphery
• B. periphery; center
• C. ventral ; dorsal
• D. dorsal ; ventral

Answer 1

The correct option is A center; periphery

The first formed xylem elements are called proto-xylem and the later formed xylem is called meta-xylem.
In both monocot and dicot stems, the proto-xylem lies towards the center (pith) and the meta-xylem lies towards the periphery. The stem which exhibits this type of xylem arrangement is said to be endarch.
