Slime molds, like fungi, use spores to survive and spread to new
sources of food. Spores are not seeds. The hard shell of a seed contains
the very small beginning form of its plant, plus some food to help the
little plant get started. A seed is made of many cells, and a single seed
is visible to our eyes.
Most spores are single cells protected by a cell wall. Some spores are made of several cells, but the largest spore is still smaller than the smallest seed (made by orchids). A single spore is too small to be visible to our eyes.
There is no microscopic slime mold inside a spore. A spore contains all the chemicals needed to make its kind of organism. When conditions are right, the spore starts to grow and creates a new plasmodium, the slime mold individual.
