Single-cell organisms, also called protists (because they are placed in the kingdom Protozoa) contain all the devices necessary for life in a single cell. This would include devices for ingesting food, moving from place to place (in those that are motile), and eliminating waste, and possibly even defence mechanisms. The one cell of these organisms is not dependent on any other cell to survive.
Human cells, on the other hand, each perform specific functions, are not self contained, and rely completely on the entire system, or a good part of it, for survival. A single human cell, removed from the body will not survive long.

The cells of a multicellular organism are usually specialized for different jobs. For instance, the human body contains nerve cells, bone cells, muscle cells and many more. A single celled organism has to do everything in one cell, so each tends to be like all the others.
a single celled organism's DNA is floating around in the cell. the Bodies has a nucleus in which DNA is stored. that is 1 of the key differences
the human body has lots of different kinds of cells and a single cell is just one kind of cell
A single cell organism can survive independently. A single cell of a multicellular organism cannot survive independently.

One difference between epithelial cells and muscle cells is their location in the human body. Epithelial cells are skin cells on the outside of the body. Muscle cells are located in the muscle under the skin.

It is the excretory opening at the end of the alimentary canal on the back end of a human's body in between the two buttocks.
The male and female body systems differ in a few key ways. While there are some similarities there are also some distinct differences in the way the two genders bodies are built and function. Following are some of the main differences between male and female body systems: The male body typically has more muscle mass than the female body. The male hormone levels are higher than the female hormone levels. The male body typically has a higher percentage of body fat than the female body. The female body has a larger percentage of water than the male body. The male body has a higher bone density than the female body. The male body typically has a higher metabolic rate than the female body.These differences between male and female body systems are due to the differences in hormones and the way the body responds to those hormones. The male and female bodies are designed to function in different ways so it is important to be aware of these differences and take them into consideration when developing a health plan.

There are a number of differences between the impact of caffeine on the human body and on the spider's body. Caffeine will energize a human and kill a spider.

For the human body, the female ovum.
There is a major difference between an appendix in a human and a cat. Namely, cats do not have an appendix, while people do. The appendix has no use within the body, but can sometimes become infected and will need to be removed.
