An Amoeba and a Protozoa are both one cell organisms.
An example of a living thing that has one cell with a nucleus is a protist, such as an amoeba or paramecium. These single-celled organisms have a defined nucleus that houses their genetic material.
algae and bacteria
Hjeieidid
multicellular
One example would be the red blood cell, though in some animals such as birds they do have a nucleus per cell.
a prokaryote (bacteria, for example).
An example of a living thing that has one cell with a nucleus is a protist, such as an amoeba or paramecium. These single-celled organisms have a defined nucleus that houses their genetic material.
If a living organism is only one cell, then it is unicellular. Any singular bacterium serves as an example.

One example is the cell wall common to most bacterial organisms. Another is the cell wall surrounding fungi. A third is the plant cell wall.
It makes the food for the plant. (The chlorophyll in the cell)
Thermocouple is one example. Photo voltaic cell
Cell organelles are the cells itself so they are the same thing. One doesn't do anything for another since they are the same thing.
