Answer
Monocotyledonous plants (monocots) have scattered and closed vascular bundles. Key characteristics include:
Scattered arrangement: Vascular bundles are randomly distributed throughout the stem's ground tissue rather than arranged in a ring, as seen in dicots.
Closed vascular bundles: They lack cambium (lateral meristematic tissue) between xylem and phloem, preventing secondary growth. This means monocot stems generally cannot increase in girth through secondary thickening.
Examples of monocots include grasses (wheat, rice, corn), palms, lilies, orchids, and bamboo. This vascular pattern is one of several distinguishing features of monocots, along with parallel leaf venation, fibrous root systems, and floral parts in multiples of three.
