Answer:
I am whole but incomplete. I have no eyes, yet I see. You can see, and see right through me. My largest part is one fourth of what I once was.
I hide but my head is outside.
I'm very tempting, so its said, I have a shiny coat of red, and my flesh is white beneath. I smell so sweet, taste good to eat, and help to guard your teeth.
I never was, am always to be. No one ever saw me, nor ever will. And yet I am the confidence of all, To live and breath on this terrestrial ball.
