The relationship is usually expressed as a ratio: surface area divided by volume. Small cells have a large surface area to volume ratio, whilst large cells have a much smaller value. This is important because the cell absorbs the things it needs, and gets rid of what it doesn't need, through the surface. If the cell gets too large, not enough exchange can take place to keep the cell going, so there is a natural limit on the size to which a cell can grow.
cell membrane
the same relationship as between humans and the universe.
Both have the cyoplasm

Living beings contain cells. Cells are required for Life. Ergo, Cells are a part of Life.
The relationship between cells,organs, and systems would be many cells make up tissue, many tissues make up an organ, many organs make up an organ system, and organ systems make up and organism.
The relationship between the radius and surface area depends on the shape and that is why some cells are spherical while others are flattened. The greater the SAV ratio of an object, the greater the scope for surface reactions of the object with its surroundings.
Hypothesis
Cells are of a small size because of consideration of the proportional relationship between surface area and volume. The size of cells also becomes a benefit when considering the rate at which cells die and are being replaced.
The relationship between the parasite and host is that they share they same body, with the parasite living off the hosts cells and energy etc.

They are genetically different from one another and from the original cell.
