3. 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!

4. Gymnosperms have “Naked Seeds”
The male pine cone
contains pollen
The female pine cone
is the typical woody cone; it
contains the eggs or ovules

5. Mature ovulate cones and seeds

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