As a cell grows bigger, its internal volume enlarges and the cell membrane expands.
Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.Finally, at some point, there is just enough surface available to service all the interior.
if it is to survive, the cell must stop growing. The important point is that the surface area to the volume ratio gets smaller as the cell gets larger.
Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane
fast enough to accommodate the increased cellular volume.
When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function.
That is why cells are so small.
Cells have a size limit because larger cells have more difficulty transporting nutrients and waste effectively due to their increased surface area-to-volume ratio. The cell membrane can only support a certain amount of activity and maintain proper function within a limited size range. Additionally, larger cells require more energy to maintain their functions, making them less efficient as their size increases.
This size restriction is due to the surface area to volume ratio (SA:V). As the volume of the cell increases, the surface area does not increase at the same rate (to test this, calculate the SA:V for varying sized cubes). For a cell to function effectively it needs to be able to transport molecules in and out of the cell, so the smaller the cell the more effectively it can carry this out.
The bigger the cell, the thicker the cell membrane and the farther oxygen has to travel to get to where it's needed. It is easier for a small cell to receive oxygen, because it doesn't have far to travel.
Think if you had two solid spheres that you placed in dyed water. One sphere was big, and the other small. These spheres would absorb the water at a constant rate. Which sphere would be completely colored (from the surface to the center) because of the dye? The small one would be completely dyed before the large one. Now think of this as a cell as the spheres and the dyed water as oxygen.
Cells typically have a size range of about 1-100 micrometers, with some exceptions. Cells like ostrich eggs or large nerve cells can be visible to the naked eye, while bacteria and viruses are much smaller. The size of a cell is primarily determined by its function and the need to maintain a proper surface area-to-volume ratio for efficient transport of nutrients and waste.
No, the size of the cells in a potato is generally similar regardless of the size of the potato. The difference in size between a large and a small potato is due to the number of cells present, not the individual cell size.
No, they are about one tenth of a cells size.
Nuclei can vary in size depending on the type of cell. Generally, the nuclei of cells within the same species are similar in size, but there can be variations between different types of cells. Some cells, like muscle cells and some liver cells, may have multiple nuclei.
No. Viruses are smaller than cells. If a cell were the size of a basketball, then a virus would be about the size of a penny.

diffusion and osmosis limit the size of a cell by how fast is can move
the size limit to ab beagle show dog is 15 in or under
no
the thing people limit the size is land, water, food, and climate.
Their size limit
The largest contributor to the limit on a cell's size is the ratio between its volume and its surface area. Because cells acquire nutrients through their membrane (surface), it is more favourable for a cell to have more surface. This can be accomplished by splitting the cell into 2 cells. The combination of the 2 cells has more surface area to absorb nutrients, than the surface area of a single really big cell. Thus cell's are limited in size by their need to be able to intake nutrients, which is accomplished by dividing into smaller cells.

Diffusion and osmosis are processes by which substances move into and out of cells. As cell size increases, the distance that substances must diffuse across also increases, making it harder for cells to efficiently exchange materials. Additionally, larger cells may struggle to maintain proper osmotic balance due to increased demand on their membrane and organelles.
There is no limit to the number of cells you can merge into a single cell.
