Seed

Real World Example

Imagine trying to keep a fragile piece of glass safe while moving to a new home. Just as you might wrap the glass in bubble wrap and place it inside a box to protect it during the journey, a seed serves as a protective casing for a plant embryo. The protective covering of the seed acts like the bubble wrap and box, shielding the delicate plant embryo inside, ensuring it remains safe until conditions are right for it to grow, much like how your wrapped glass remains intact until you reach your new home.
