im sure ants can think, i'm sure worms and think, what about amebas or those other single cell organisms. protozoa or whatever, and paramecium. don't they need to think to find food? so what about the cells in our bodies? they have to decide what to do don't they? they have to know what to let into the cell and what to let out. how does your skin know that it has to heal? I sure as heck don't tell it to. it does it by itself. so am i built up of millions of tiny thinkers? In high school biology i was taught that the nucleus of a cell is the "brain" of the cell, or control center. how can it do this job without a mind?

The cell doesn't think. It merely reacts to chemical signals that it detects. The same goes for protozoa. I strongly doubt that ants and worms do also. I doubt that there's enough nervous tissue to form an actual thought. They are certainly more complicated than protozoa, but they work on instinct, not by making conscious decisions.
The lesson that you were taught in your high school biology class was an analogy, not the literal truth. The cell nucleus does control what happens in the cell, but it doesn't think. It merely contains the programs that operate the cell, in the form of DNA.

cellular membrane is what distinguishes the interior the cellular from he exterior, got here across i Prokaryotic and plant cells. cellular wall - the wall exterior the cellular which protects any injury from exterior to the cellular. present day in animal and plant cellular. Nucleus - the critical area of the cellular which controls it : present day in all cells Cytoplasm : the liquid area which surrounds the nucleas : present day in all plant and animal cells.

Well, you wouldn't always have to think. For some animals and insects, it is only in their instinct, and they don't have to think. A nucleus is the manager of the cell, so you could say it does think.

It's not a literal brain, it responds to chemical stimuli, but has no neurons.

Because DNA it can make a copy of it self...
