Why do amoebas only have one cell?

Question

i need details!!!11

Answer 1

They are very simple organisms. To be a multicellular organism, the cells have to develop ways to communicate with each other. That will require more complexity.

Answer 2

It is not only amoeba which has one cell. It is actually a larger group of unicellular animals called protozoa which possess single cell. Since they are the most primitive & simple types of organisms in the evolutionary tree, they possess single cell.

Answer 3

Why? What do you mean...why? That's just how they were made, they didn't have a choice. I don't understand your question.

Answer 4

that is all they could afford

Answer 5

If they didnt they would be called parasites...

Answer 6

Amoebas are single cell animals by definition.  If it had more than one cell, it would not be an amoeba.  An amoeba functions very well as a single cell organism.
