We call these unicellular.

Unicellular
A unicellular organism is one that functions as a single unit.
unicellular
Binary fission.
They are known as Prokaryotes.
The parts of a single celled organism usually rely on what type of cell it is. A prokaryotehas a nuleouswhile an eukaryote doesn't.
In a single-celled organism (Unicellular organism), one cell carries out all the functions of the body. For example, transporting nutrients, excretion ,etc are performed by the single cell which makes up the organism. In a multi-cellular organism, on the other hand, various cells arrange or group themselves to perform certain or particular functions. They are specialized to perform any one type of function. This is what makes up tissues, organs and ogran systems in a multi-cellular organism. One group of cells performs one function. For example, blood corpuscles are of different types. One type (WBCs) helps in fighting diseases, another type (RBCs) will help in transporting oxygen to various cells and so on.
A seahorse is a multicellular organism. It is a type of fish.
depends on the organism and type of cell
The largest known single celled organism is called a "Valonia Ventricosa".These organisms typically grow in tropical or subtropical waters around the world.
The members of a single type of organism in an environment is called population.
It is not a cell. It is a multicelluar organism.
A white blood cell is not an organism because it cannot live separately from the rest of the cells making up a human being. It is, however, similar to single-celled organisms like amoebae.
