Compare spore and seed sizes.

The seeds are large in most cases. This is due to the fact that inside the seed you will germinate a plant, which can often be seen with the naked eye, as well as a certain amount of nutrients. Disputes have a different structure. Therefore they are very small. It is almost impossible to see them without the help of magnifying devices. Hundreds of spores are stored in a very small spore box above the moss. Therefore, disputes are hundreds of times less for seeds of various plants.
