Furthermore, on another vein, I don't understand this: If a cell is mostly "empty space" why is it objects appear to be solid? What causes this illusion or the cells to bound together?

Like charges repel one another. Each atom is surrounded by a cloud of electrons, and as these electrons move closer and closer together, they repel one another more and more strongly. That's the simple explanation.

A few familiar thoughts we often encounter, come to mind per questions posed here:

If a tree falls in the forest and there is no one there; does it make a sound?

The other is, the oft quoted Biblical. . ....and the Word was made flesh.

As well, a popular zen koan comes to mind: what is sound of one hand clapping?/sigh (a breath-less sigh).

Oh. . .and then there is Shrodinger's Cat. . .and a gazillion more perhaps; but brings the quantum challenges/dilemmas into focus. . .maybe?

Wow! That's real cool. I guess the next question would be how do they know to repel each other, but I could go on and on... Thanks for answering my questions. Very informative and explained in a nice informal way I can grasp. Very good.

I never was much interested in this stuff before, but once I found out from quantum physics a particle could be two places at once that sold me! It's quite fascinating. It's almost as if we truly are living in an illusion.
