The seed can't be an interface because it needs to contain state. For
instance the progress towards becoming the respective fruit.

The seed needs to be aware of the fruit it came from to access the fruit's
DNA to inherit the traits of that fruit when it grows into a fruit of its
own. (Please note, that it's just an example).

A fruit can have multiple such seeds, each of which must have it's own
state and connection to the same fruit they came from.

So, we start off by inheriting from Fruit, defining the properties of that
fruit (It's an Apple, it's delicious and it goes great in a pie). Then we
define several different types of Apple seeds, each of which need access to
the apple.
