There are two types - Prokaryotes and Eukaryotes. Prokaryotes are the bacteria and Eukaryotes are the cells.
whats the word for single celled organisms without nuclei such as esherichia coli which live in the human body
Monerans I think
The human body is many animal cells. Bacteria are single celled organisms. The cell is the smallest partical that is living. Animals are more then one animal cell. Plants are more then one plant cell. An organism can be single celled or multicellular, but all life consists of cells. In higher organisms, the cells diferentiate and are not capable of living alone. Protists are single celled organism which can have animal and / plant characteristics.
there are many ways.. some like amoeba feed by phagocytosis, while other prokaryotes feed by simple diffusion
Organisms are made up of different kinds of cells and tissues. The more complex the organism, the more complex the makeup. For example, a single-celled organism has just one cell that comprises it, and a human has cells, tissues, organs, and body systems that enable the body to function. Despite the vast differences from a single-celled paramecium and a human, both are organisms, and both are made up of cells and tissues.

They have Millions of bacteria live on the human body.
They are living, but they are not organisms. Cells are the "building blocks" of tissues, which group together into organs, which group together into organ systems. Those organ systems comprise an organism. The individuals cells are not organisms themselves.

A single or many celled reproductive body of an organism that can create new organisms.
Single-celled organisms are sometimes asexual. Another example would be spores, which do not have defined genders.
Single-celled organisms, such as bacteria, are often prokaryotes and as stated in name are made of only one cell.Multi-cellular organisms, such as plants and animals (eukaryotes), have a higher degree of specialisation (i.e we have epithelial cells, muscle cells, etc). The cells can work and function together to create a living organism.EX: a human -- cell then tissue then organs then organ systems and then the human body.

People and single-celled organisms have something in common.Something that they have in common are that they both have a cell.They both also have bacteria.As you can see people and singe-celled organisms.

There is a limit to how big a cell can get, and that nearly always means we need a microscope to see them, Size is limited by the need for substances to diffuse in and out of the cell. If it gets too big there simply isn't enough surface to allow enough exchange of substances for the cell to maintain its life processes.
Yes, it is. The somatic (body) cells of multi celled organisms that reproduce sexually contain pairs of chromosomes.
