Because if they did not separate nutrients and waste could not move acroos the cell membrane quickly enough to send it throughout the entire cell. This would cause the cells to die. That is why they divide instead of growing larger.
Nutrients and oxygen have a hard time entering and exiting the cell when it is large.
Moving needed materials in and waste products out
The larger a cell becomes, the more demands the cell places on its DNA. In addition, the cell has more trouble moving enough nutrients and wastes across the cell membrane
Compared to small cells, larger cell have more trouble moving needed materials in and waste products out.

why can small cells exchange substances more readily than large cells?
With smaller cells, there is a greater surface area.
The animals cells do not have a cell wall whereas plant cells do. The plant cells have a large vacuole with cell sap whereas animal cells have many small vacuoles with no cell sap. The plant cells have chloroplast whereas animal cells do not.
Yes, respiration rates for large organisms are generally higher compared to small organisms. Large organisms require more oxygen than small organisms.
Compared to other planets, yes it is small. But compared to a house, no, it is very large...
Animal cells have small vacuoles, whereas plant cells have large vacuoles.

Comets are generally fairly large, dozens or hundreds of miles in diameter. Small compared to planets or asteroids, but large compared to meteors or dust.

yes they are small and they have no nucleus unlike eukaryotic cells that do have a nucleus and are large.
It compared in size to the large intestine it is about twice as small
no. a large potato justhas a larger amount of cells.
Egypt is a bigger country than England in terms of land area. Egypt is approximately 3.5 times larger than England.
VERY small.
large compared to alabama and Rhode island
It depends on the context. Compared to an atom it is huge, compared to the sun it is tiny.
