26. When living yeast cells were placed in congo red dye and examined under the microscope, the yeast cells remained colorless. However, when placed in methylene blue, they became blue. Later, dead yeast cells were placed in congo red dye. These cells turned red. Explain these three observations.

27. A process that would result in the
movement of these molecules out of the
cell requires the use of

process?

29. Which cell is using energy for the process shown above?
Cell A
What is the name of this process?
Active Transport
