1.	In the preparation of samples for SEM, the specimens are air-dried by a process of critical-point drying.(a) True(b) FalseI have been asked this question in quiz.This question is from Techniques in chapter Techniques in Cell Biology of Cell Biology
Answer» The correct ANSWER is (a) True The best I can explain: For sample preparation of SEM, the BASIC requirement is PRODUCING specimen that has the same shape and surface properties as that of the living cell and at the same TIME is devoid of any fluid for viewing under the vacuum.
