Answer Details
A wide pith in the centre of the internal structure of plants is common to dicot stems and monocot stems. The pith is the central portion of the stem, surrounded by the vascular tissue, and consists of parenchyma cells that store food and water for the plant.
Dicot stems and monocot stems are two types of plant stems. Dicot stems have a distinct pith in the center, surrounded by vascular tissue arranged in a ring. Monocot stems, on the other hand, have scattered vascular bundles throughout the stem, with no distinct pith in the center.
Therefore, the presence of a wide pith in the center of the internal structure of plants indicates that the stem in question is a dicot stem or a monocot stem.
