Question

what is the purpose of tanic acid in cell wall staining?​

Answer 1

Explanation:

Tannic acid has been found to react as a mordant between osmium tetroxide and lead citrate, forming a Ȝstabilizing matrixȝ within the cells. Blastospores appeared to have an improved comprehensive ultrastructural appearance, a result of the tannic acid-matrix preserving cellular components for electron microscopy.
