1.	In TEM, the tissue is stained by floating on drops of ______________________(a) hydrocarbons(b) slow-molecular weight stains(c) heavy metal soutions(d) oil immersionThis question was addressed to me in homework.The origin of the question is Techniques topic in chapter Techniques in Cell Biology of Cell Biology
Answer» Correct option is (c) HEAVY metal soutions The explanation is: The tissue is stained by floating on drops of uranyl acetate and LEAD citrate (heavy metal solutions). These solutions when bound to the specimen, PROVIDE the density required to scatter the electron BEAM.
