What is a monocot plant?

• A. It has two cotyledons, parallel veins
• B. It is a broadleaf seedling with two leaves as they emerge
• C. It has one cotyledon, branched veins and in multiples of 3
• D. It is a grass

Answer: (C)

Monocots are plants that start from a seed with one cotyledon and usually have leaves with parallel veins, plus floral parts that occur in multiples of three. The choice that mentions one cotyledon and multiples of three aligns with these defining features, making it the best fit among the options. The note about branched veins isn’t typical for monocots—that parallel venation is a key trait—so the strongest takeaway is the single cotyledon and three-part floral pattern. For contrast, dicots usually have two cotyledons, net-like (branched) leaf veins, and floral parts in multiples of four or five.
