GERMINATION
A seed might look dead, but it isn't. Seeds rest quietly until all things are right for it to begin "germination" which means "begins to grow."
Timing is everything.
When conditions are right...
...the first step in a seed’s
growth can begin...
taking in water.
As water is taken in, the seed swells bigger and bigger until the coat splits apart. Air can then get to the seed. The oxygen in the air helps the baby plant burn the food packed inside the seed. Burning the food produces energy. The baby plant uses the energy to grow.
The root begins to grow downward and the baby stem begins to curl upward. Soon the baby plant isn't a baby anymore.
