1) Embedding allows us to obtain thin sections from tissues because the samples are hardened.

2) Embedding is the only way to harden a sample to get sections.

3) Paraffin hardens the samples by becoming solid.

4) Resins are embedding media that get solid by polymerization.

5) Epoxy resins and paraffin can be dissolved in water.

6) Paraffin gets the samples harder than resins do.

7) Paraffin embedding yields sections to be observed with the electron microscope.

8) To stain tissues obtained from resin-embedded samples, resin has first to be removed.
