• Cotyledon – seed leavesCotyledon – seed leaves• part of the embryopart of the embryo• the first leavesthe first leaves• transfer nutrients to the
embryo
Monocot – I cotyledon Ex) corn
Dicot – 2 cotyledons Ex) Kidney and Lima beans

Monocots
Leaf veins parallel
Vascular tissue scattered
Flower parts in threes
Ex) lilies, grasses, corn

DicotsDicots
Leaf veins netlike
Ring of vascular tissue
Flower parts in fours or fives
Ex) trees, geranium, cacti
