Here's why:
* Spores are specialized reproductive cells: They are designed to survive harsh conditions and later germinate to form a new organism.
* Complete genetic blueprint: A spore must carry the full set of genes needed to develop into a new organism, just like a seed.
* Variations in size: The amount of DNA in a spore can vary greatly depending on the species. Some spores might have less DNA than others, but they still contain the complete genetic information.
Therefore, the key factor is not the quantity of DNA, but the presence of a complete and functional set of genes that can guide the development of a new individual.
