At what point can a mass of cells be considered a living being?

Some time ago I was talking to my brother about abortion, and one thing he said is: at what point can we consider a mass of cells a human and living being? Is there an exact point at an exact time where some cells become a living thing? How can we decide whether or not abortion is moral? Is a living being _living_ if it is conscious? And what about people in coma or vegetative state?

Single cell organisms are a thing. A better question might be: When are these cells considered protected life?

When does consciousness actually occur is another great question. What is consciousness, exactly? Is it a will? Or a lens? Or a complex illusion that looks like one of the aforementioned? Does a sphex have consciousness? A dog? An amoeba?

Is unconsciousness "dead brain", or "sleep state brain"? Hard to tell if you don't have a definitive answer for what is consciousness. 

Everything is a moral issue if you frame it as such. How you frame it is pro and con, by definition of morality. 

Is abortion right or wrong? Probably depends highly on the circumstances. Beliefs about which life is worth protecting and the definition of, or weight given to consciousness, are also major considerations when examining the morality of abortion.
