[Closed] a rediculous hypothetical question regarding plants

I have always struggled with something which at first glance appears a very basic concept.

Plants have DNA.

However, when I let my fertile little mind explore this fact I start to wonder about the possibilites of playing around with this DNA.

I realise that plant life lacks a backbone/nervous system as we know it, but faced with quotes like ''humans are 98% fruit fly'' makes me wonder if with a little genetic recoding, could we create a daffodil with working eyes?
Could we put ears on an oak tree?

Is it possible to stick a brain in a pagonia?

Can someone cleaver please put me out of my misery
