Final answer:
Corn develops from a seedling with a single cotyledon, displays parallel veins on its leaves, and produces monosulcate pollen. These characteristics classify it as a monocot, which is a type of angiosperm.
Step-by-step explanation:
Corn develops from a seedling with a single cotyledon, displays parallel veins on its leaves, and produces monosulcate pollen. These characteristics are all consistent with monocots. Monocots are a type of angiosperm, which is a flowering plant that produces seeds enclosed within a fruit or seed pod. Corn belongs to the monocot group because it has a single cotyledon, parallel veins on its leaves, and monosulcate pollen.
