Question

Explain the conditions that are needed to allow a seed to germinate.

Answer 1

Seeds require moisture, light, temperature, dormancy, and scarification for germination. Some seeds have a hard seed coat that needs to be softened or scratched before germination. This can be achieved through mechanical or chemical processes.

Step-by-step explanation:

In order for a seed to germinate, several conditions need to be met:

1. Moisture: Seeds require water to rehydrate and activate enzymes needed for germination.
2. Light: Some seeds require light to germinate, while others need darkness.
3. Temperature: Different seeds have different temperature requirements for germination. Some seeds need a cold treatment, while others need a warm treatment.
4. Dormancy: Many seeds have a period of inactivity called dormancy. Dormancy helps seeds survive unfavorable conditions until the environment becomes favorable for germination.
5. Scarification: Some seeds have a hard seed coat that needs to be softened or scratched before germination. This can be achieved through mechanical or chemical processes.
