Single Celled Organisms

Question

Do they literally have just one cell, or do they have many cells but all of one type?

How do they manage to do things like move, eat and have some basic form of instinct with only one (or one type) of cell? What things are physically/biologically impossible for a single celled organism to be able to do (that a multi celled organism could do)?

> Do they literally have just one cell

Yes.

They move by changing shape or swimming using little hair-like organelles called flagella. The ones that eat other organisms do it by absorbing the organism into themselves and metabolizing it.

They cannot play country music, as they do not know three chords.
