Which statement is true about dicots?

• A. Two cotyledons
• B. Flower parts in multiples of threes
• C. Vascular tissue in a ring around the stem
• D. Fibrous root system

Answer: (A)

Dicots are distinguished by having two seed leaves, or cotyledons, when they germinate. This seed feature is the most straightforward way to identify dicots and why two cotyledons is the true statement. Monocots, in contrast, have a single cotyledon. The other options describe traits that are typical of monocots (flower parts in threes and fibrous root systems) or a stem arrangement that is common in dicots but not the seed-based identification focus of this question. So the true statement about dicots, emphasized in basic agriscience, is that they have two cotyledons.
