Seeds need certain environmental conditions to germinate, but they also have internal factors that play a role.
Here's what's essential for germination:
* Water: Seeds need moisture to soften the seed coat and allow the embryo to access nutrients.
* Temperature: Most seeds have an ideal temperature range for germination. Some seeds require a period of cold (stratification) before they will germinate.
* Oxygen: The embryo needs oxygen for respiration to grow.
* Light: Some seeds require light to germinate, while others need darkness.
Internal factors also matter:
* Dormancy: Many seeds have a period of dormancy, during which they won't germinate even if conditions are right. This can be caused by a hard seed coat, hormonal signals, or other factors.
* Viability: The seed's age and storage conditions can affect its ability to germinate. Older or damaged seeds may be less viable.
So, while good environmental conditions are crucial, it's not just about the environment. The seed itself needs to be ready to germinate, and internal factors play a significant role in this process.
