What are the special features of seven different seeds?

Different seeds possess unique features that aid in their survival and dispersal. For example, dandelion seeds have fluffy, parachute-like structures that allow them to be carried by the wind. Sunflower seeds have a hard outer shell that protects the embryo while providing nutrients. Lotus seeds can remain dormant for centuries, germinating only when conditions are favorable. Maple seeds have a wing shape that helps them glide away from the parent tree. Coconut seeds can float on water, enabling them to travel across oceans. Pea seeds have a smooth surface for easy dispersal by animals, while acorns have a hard shell that protects the seed from predators.
