The pollen from the male cone fertilzes the female
egg to produce the seed inside the cone.
Cones are made up of many scales that serve to
protect the seeds as they mature.
The seeds grow at the bottom of the scales.
The seeds can grow for two years.
When it is time, the cone opens up and falls to
Wind blows the seeds around. Small Animals
like Chipmunks eat the cone and seeds get
spread even more.
The seeds will lay in soil and be watered by rain.
The seeds will grow into small plants called
The seedlings will grow to become small
conifer trees called saplings. These sapling trees
are too young to produce cones.
The small saplings take a long time to grow to be
a mature Conifer. It can take as long as 70 years
Once the tree is mature, it will produce cones
again that contain the seeds and the cycle will
