What is a Seed? • The embryo of a plant
• The pollen is the “sperm” or male gamete
• The egg is found within a flower if the plant is an angiosperm; or the female cone if the plant is a gymnosperm
• Fertilization results in an embryo or SEED!

Gymnosperms have “Naked Seeds”
The female pine coneis the typical woody cone; itcontains the eggs or ovules
The male pine conecontains pollen

Angiosperms have male and female parts (think of lab last
week!)

• Let’s investigate…..
