What is dormancy?

• a structure of behavior that helps organisms survive and function better in its environment

• a period of inactivity in which a plant or seed does not grow in order to survive unfavorable environmental conditions

• when a seed begins to sprout

• plant growth in response to a stimulus

When a seed begins to sprout:

• germination

• dormancy

• pollination

• adaptation

• germination

• dormancy

• tropism
