Seeds Monocot vs. Dicot Accelerated Biology
2
Seed Anatomy Seed coat – protects embryo from injury and harsh environment develops from the outer layers of the ovule Endosperm – portion of seed that stores food (energy) for the developing embryo What types of plants reproduce through seeds? – gymnosperms and angiosperms How do mosses and ferns reproduce? – spores
3
Seed Anatomy Cotyledon – seed leaves part of the embryo
the first leaves transfer nutrients to the embryo Monocot – I cotyledon Ex) corn Dicot – 2 cotyledons Ex) Kidney and Lima beans What types of plants reproduce through seeds? – gymnosperms and angiosperms How do mosses and ferns reproduce? – spores

6
Seed Anatomy Radicle – embryonic root (becomes root)
7
Seed Anatomy Epicotyl – part of the shoot stem above cotyledons
Hypocotyl – part of root stem below cotyledons
8
Monocots Leaf veins parallel Vascular tissue scattered
Flower parts in threes Ex) lilies, grasses, corn
9
Dicots Leaf veins netlike Ring of vascular tissue
Flower parts in fours or fives Ex) trees, geranium, cacti
