Seeds need water, oxygen, and proper temperature in order to germinate.
Explanation:
- Seeds remain dormant or inactive until the correct circumstances for germination are met. To germinate, all seeds require water, oxygen, and the right temperature. Some seeds, however, require adequate lighting. Some seeds germinate better under bright light, while others need to remain in the dark to germinate.
- Water and oxygen are taken in through the seed coat when it is exposed to the right conditions. The cells of the embryo begin to expand. The seed coat then splits open, revealing a root, or radicle, followed by a shoot, or plumule, which contains the leaves and stem.
