Yes , bacteria , protozoa and many algae contain only one cell .
Unicellular organisms contain just one cell, example: amoeba, bacteria. Multicellular organisms are made up of more than one cell which includes everything other than the unicellular organisms.
Some do and some do not. Bacteria, for example, do not contain nuclei and are known as prokaryotes. Yeast, on the other hand, do contain nuclei and are known as eukaryotes.
An eukaryotic cell just means that it has membrane bound organelles and a nucleus. single cell organisms are organisms that are solo, they aren't cell specialized. Single cell organisms can be eukaryoic or prokaryotic (no membrane bound organelles and no nucleus) cells.
Unicellular organisms
cell classification can be use full for ideynifing organisms if you know what kind of cell the organism has and can identify it to a cell just like it.
Unicellular organisms and gametes
The cell membrane - without which cytoplasm is meaningless - serves to contain cytoplasm just as a wall would contain a city.
Eukaryotes have a nucleus While prokaryotes dontProkaryotes are organisms that are made up of one cell. The most common example of this would be bacteria. Eukaryotes are organisms that are made up of multiple cells. Almost any animals you can observe normally are eukaryotes. Think of it this way: a PROkaryote is PROfessional, so they can stay alive with just one cell.

Plastids,cell wall and large central vacuole just in planet cell;centrioles just in animal cells.
Yes. They are referred to as single-celled organisms. Some examples are bacteria and many other prokaryotes. blaine allen reeder was here.
This varies enormously from species to species. Most single cell organisms can even be considered immortal. they just divide in two with neither cell being identifiable as being the "new" cell.
