The ________ Stain Makes Use of Malachite Green

Question

The ________ stain makes use of malachite green.
A) negative
B) flagellar
C) endospore
D) electron microscopy
E) acid-fast

Accepted Answer

The endospore stain is used to distinguish endospores, which are highly resistant structures produced by some bacteria, from the rest of the cell. Malachite green is used in the staining process to penetrate the endospore and then heat is used to lock the green dye inside the endospore. This allows for easy identification of endospores under the microscope.
