Size in cell biology

?
Do cells carry on growing indefinitely?
No, cells reach a certain size and then begin to divide
1 of 5
What happens if a cell becomes too large?
A cell which is too large will develop problems because its surface area:volume ratio will be too small.
2 of 5
What can a small surface area:volume ratio cause?
A small surface area:volume means that a cell is unable to uptake essential materials and excrete waste products fast enough. The same concept applies for heat.
3 of 5
What are the units used to measure the size of cells?
Metres, millimetres, micrometres, nanometres
4 of 5
How is magnification calculated?
The size of the image is divided by the size of the specimen
