Plants are an interesting case. It's a pretty simple theory - plants need more DNA because they can't change their location. If conditions change around them, they can't just get up and move like an animal. Instead, they have to have dormant DNA that doesn't get activated unless the environment changes. They can't change their locations, so they have to change themselves.
