Question:

Dicot stem share a common feature with monocot stem that is both have

Options:

1. Well developed large pith
2. Conjoint vascular bundles
3. Open vascular bundles
4. Pericycle and endodermis

Solution:

Both dicot stems and monocot stems share the feature of having conjoint vascular bundles. Conjoint vascular bundles are bundles in which xylem and phloem are arranged in a ring, with phloem located towards the outside and xylem towards the inside. This arrangement is common in both dicot and monocot stems. Option 1 is incorrect, as dicot stems typically have a small pith, while monocot stems may have a large pith. Option 3 is incorrect, as open vascular bundles are characteristic of monocot stems, where the vascular bundles are scattered and not arranged in a ring. Option 4 is incorrect, as pericycle and endodermis are present in dicot roots, not stems. In monocot stems, there is usually no distinct pericycle and endodermis.
