1. Seed Coat: The seed coat, also known as the testa, is a protective outer layer that shields the seed from physical damage and disease. It also prevents water loss, ensuring that the seed remains dry and does not germinate prematurely. This adaptation is crucial for survival in dry land conditions where water is scarce.

2. Dormancy: Seeds have the ability to enter a state of dormancy, which is a period of halted growth and development. This allows them to survive in unfavorable conditions, such as periods of drought. When conditions become favorable again (e.g., the arrival of rain), the seed "wakes up" from its dormant state and begins to germinate.

3. Food Storage: Seeds contain an endosperm, which is a tissue that provides a food source for the developing plant embryo. This allows the seed to sustain itself during the germination process when external resources may be limited. In dry land environments, where nutrients and water can be scarce, this internal food source is a key adaptation for survival.
