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.

What are the key differences between the posterior and anterior regions of the human body?
The key differences between the posterior and anterior regions of the human body are their locations. The posterior region is the back side of the body, while the anterior region is the front side. Additionally, the posterior region typically has larger muscles and more bony prominences compared to the anterior region.
What are the key differences between the front and back anatomy of the human body?
The key differences between the front and back anatomy of the human body are the location of major organs and structures. The front of the body typically houses organs like the heart, lungs, and stomach, while the back contains the spinal cord, muscles, and bones. Additionally, the front of the body is more vulnerable and exposed, while the back provides protection and support for the body.
What are the main differences between the endocrine and exocrine systems in the human body?
The main difference between the endocrine and exocrine systems in the human body is that the endocrine system secretes hormones directly into the bloodstream to regulate various bodily functions, while the exocrine system secretes substances through ducts to the outside of the body or into body cavities.
What are the key differences between posterior and anterior positioning in the human body?
The key difference between posterior and anterior positioning in the human body is their location relative to the front and back of the body. Anterior refers to the front side of the body, while posterior refers to the back side. This distinction is important for understanding anatomical terms and directions in medical and scientific contexts.
What are the genetic differences between bacteria cells and human body cells?
One key genetic difference is the presence of a nucleus in human cells, which bacteria lack. Human cells have linear chromosomes enclosed within the nucleus, while bacteria have a single circular chromosome located in the cytoplasm. Additionally, bacteria may have plasmids, small circular DNA molecules that are often absent in human cells.
What is the differences between the frog stomach and the human stomach?
human stomach is located somewhere on the left center of the body
