Monocots � Examples: Rice Ø Corn Ø Wheat Ø Lilies Ø

Monocots � Features: � Long narrow leaves with parallel veins � Flower parts come in parts of 3 � Scattered bundles of vascular tissue in stem

Angiosperm - Dicot � A flowering plant whose embryo has: � 2 cotelydons

Dicots � Features: � Leaves with netlike veins � Flower parts come in multiple of 4 or 5. � Ring of vascular tissue in stem

Dicot � Examples: � Vegetables � Peanuts � Deciduous tree
