Before a seed can form, pollination and fertilization must occur.

What three thing are required for a seed to germinate?
Water, Oxygen, Temperature
what major events occur in each of the three stages of germination?
imbibition (rapid water absorption), respiration (activation of metabolism and enzyme activity), and radicle emergence (root protrusion).
what is a plant that no longer depends on the cotyledons for nourishment called?
A seedling
How long does it take for an annual to produce seeds?
