Why is it more accurate to measure living organisms than stained specimens?

 Staining can sometimes have an effect on size because it may cause the organism to shrink or swell.

Thank you for posting your question here at I hope the answer will help you. Feel free to ask more questions.

Because stained specimens gets damaged or distorted and hence give inaccurate information.

Explanation:

To stain the specimens and the extensive procedure is followed which involves procuring the sample, fixing them and the staining and mounting them for observation.While staining an organism, it needs to be put into a suspension liquid, then fixated in the heat so that it will stay on the slide.This process of suspending in fluid and heating can damage the cells or distort their shape and structure as proteins are heat sensitive and thus, the information obtained through stained specimens is less accurate than provided by living organisms.
