Question
During ________________, the water and gas-resistant seed coat inhibits water intake and oxygen exchange.
- Seed germination
- Water
- Seed dormancy
- Fungus
- Embryo
Hint:
- Seed dormancy is the condition of a seed when it waits for the suitable conditions to germinate.
The correct answer is: Seed dormancy
Seed dormancy
- During seed dormancy, water and gas resistant seed coat stop the entry of water and exchange of oxygen through seed coat.
- During seed dormancy seed coat prevents it from the harsh conditions.
- A seed doesn't germinate untill it doesn't get the suitable conditions for germination.
