A Spore is usually a small single-celled reproductive unit capable of growing into an adult individual independently, similar to a seed. In this photo we see clumps of orange fern spores on the underside of a sword fern. For scale the blue footed booby is about 1.5 inches tall.

Seed dispersal is the means by which a parent plant spreads its child seeds about the environment. We can see here this dandelion plant has developed a way to disperse its seeds using the wind. The white tuft contains several seeds attached to a feather-like head, which pulls the seed up and away if the wind blows hard enough.
