Quizplus · Accepted Answer

The apoplast is the extracellular space outside the plasma membrane but inside the cell wall in plant cells. Therefore, if the stain is only coloring in the apoplast, only the cell walls will be colored. The plasma membrane, plasmodesmata, cytoplasm, and vacuoles are all inside the apoplast and should not be colored by the stain.
