It is optional. I prefer reporting " reasonable " digits.

The accuracy of the measurement device determines the number of significant figures that should be retained in recording measurements.
as often as possible
You would need to record to the 0.1 cm, then estimate the next significant figure. So you should have a measurement to the 0.01 cm.

The accuracy of the measurement device determines the number of significant figures that should be retained in recording measurements.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Out of all the measurements used in the calculation, find the one with the least number of significant digits. This will be the limiting factor of how many significant digits the answer should have.
A ruler or scale should not be read to less than the smallest graduation. In practice, in-between measurements can be estimated but they are not significant.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
to .0251 grams or 2.51 x 10-2 grams
Three significant figures: two before the decimal point and one after.
because in a dried smear the size of the microorganisms reduce by almost 10 to 20% from the dimensions of the living microorganism.
The accuracy of the measurement device determines the number of significant figures that should be retained in recording measurements.
measurements should be made precisely to ensure accuracy (:
You can only evaluate what you have measured (or you are just making things up). Monitoring is the process of obtaining measurements.
