What differentiates dicots from monocots in terms of cotyledons?

Dicots are distinguished from monocots primarily by the number of cotyledons present in the seeds. Cotyledons are the first leaves that develop from a seed, and they play a crucial role in providing nutrients to the young plant during its early growth. Dicots, short for dicotyledons, have two cotyledons in their seeds. This characteristic is a defining feature that helps in classifying plants into these two major groups.

Monocots, or monocotyledons, on the other hand, have only one cotyledon. This structural difference has further implications for the overall development of the plant, including leaf structure, root systems, and flowering patterns. While the other choices refer to features that might differentiate monocots from dicots in areas like leaf vein arrangements and floral structures, the specific distinction based on cotyledons is crucial for identifying and understanding these two plant categories.
