Lab 8 Endospore Staining

What is the thick walled structure that some bacteria produce to survive environments not favorable for them?

• Endospores

• Cell Walls

• Cell Membranes

• cysts

The component of the endopsore that makes the endospore so hardy is

• lipopolysaccharide membrane

• mycolic acid

• dipicolinic acid

• peptidoglycan

If endospores are present in a Gram stained sample, they will appear

• purple

• pink

• green

• unstained/ colorless

The mordant in the endospore staining process is

• Gram's iodine

• acid alcohol

• heat

• malachite green

In the endospore staining process, the primary stain washes out of

• endospores

• anything that is not an endospore

• Gram negative cells

• Gram positive cells

At the end of the endospore stain, endospores will appear

• green

• pink

• purple

• colorless

When one bacterial cell is in an unfavorable environment, it may be triggered to form

• one endospore

• hundreds of endospores

• thousands of endospores

• one cyst

The primary stain in the endospore staining process is

• crystal violet

• safranin

• malachite green

• methylene blue

The counterstain in the endospore stain is

• crystal violet

• malachite green

• acid alcohol

• safranin

At the end of the endospore stain, vegetative (growing, not spores) cells will appear

• green

• pink

• purple

• colorless
