Which group includes plants with one cotyledon in seeds?

• A. Dicots
• B. Monocots
• C. Gymnosperms
• D. Angiosperms

Answer: (B)

A single cotyledon in seeds identifies monocots. The term mono- means one, and monocots are defined by having one seed leaf that appears as the seedling emerges. They also typically show parallel leaf venation, vascular bundles scattered throughout the stem, and a fibrous root system, with floral parts often in multiples of three. In contrast, dicots have two cotyledons, net-like leaf veins, vascular bundles arranged in a ring, and usually a taproot system, with floral parts in multiples of four or five. Angiosperms encompass monocots and dicots, while gymnosperms are seed plants that do not produce flowers. Therefore, the group with one cotyledon is monocots.
