If a cell gets too big it won't be able to get rid of metabolites and acquire nurishment from the environment and end up dead. Metabolites and nurishment get to the cell through cell membrane, nurishment is needed for every thing insede the cell and metabolites are made by all metabloic reactions inside the cell. Thinking geometrically, it's ratio of volume to perimeter that matters, when cell grows it's volume increases faster than perimeter (membrane) and, thus it is at some impossible for the membrane to do it's job properly.
No, all multicellular organisms have the same size cells.
No they do not. They all have the same size of cells.

We can not give you an answer as you do not give a choice. However, cells stay small because they are the right size to function properly. Perhaps you can select an answer from that.
Size does not matter as there are small peptides that are important.
All living things are made up of cells. Because they are small in size does not mean that their cell size is small. Generally cells are the same size between organisms.
No, all multicellular organisms have the same size cells.
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.
Cell division is important as related to the size of cells. This is because cell division will take a lot longer in larger cells.
No they do not. They all have the same size of cells.
they are self-reproducing
they are blood vessels that reachout to the cells
