Detailed explanation-1: -Single-celled organisms are called unicellular organisms. All prokaryotic organisms such as Bacteria, Archaea are unicellular.

Detailed explanation-2: -Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast.

Detailed explanation-3: -Euglena is a unicellular organism. It is made up of a single cell that is capable of performing all the life processes required by it to survive.

Detailed explanation-4: -A unicellular organism, also known as a single-celled organism, is an organism that consists of a single cell, unlike a multicellular organism that consists of multiple cells. Organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms.

Detailed explanation-5: -A unicellular organism is composed of a single cell. This single cell performs all the biological processes required for the maintenance of life activities of a cell. Thus, in case of unicellular organisms, all life activities are performed by a single cell.
