What is the scientific name for corn?

1. Medicago sativa

2. Triticum aestivum

3. Zea mays

4. Glycine max

The correct answer is: Zea mays

The scientific name for corn is Zea mays, which is the accepted nomenclature within the field of botany for this important agricultural crop. Zea mays belongs to the Poaceae family, commonly known as the grass family, and is characterized by its significant economic importance, particularly in food production, livestock feed, and biofuel development. The term "Zea" refers to the genus, and "mays" denotes the species, indicating that this is a specific classification within the broader taxonomic hierarchy. Understanding the scientific classification is crucial for agronomy as it helps differentiate corn from other crops and plant species. Each part of the name provides information about the plant's characteristics and its relationships to other plants. Unlike other options listed, which refer to different crops such as alfalfa (Medicago sativa), wheat (Triticum aestivum), and soybeans (Glycine max), Zea mays specifically identifies corn, ensuring clarity in communication among scientists, farmers, and agronomists regarding research, cultivation practices, and crop management.
