It would have a clear spot in the middle of the cell if you try a Gram stain, but if you use a spore stain, it would have a green spore inside of the red cell. P.S. You shouldn't wait until the night before your lab manual is due before you decide to do it.

**micro biology**

If you forgot to add the safranin to your spore stain, you would only be able to see the spores and not the actual cells. P.S. This was an easy one, the answer was basically on the lab handout, and you should have picked it up from Ms. Stafford during class.
