Answer:
Step-by-step explanation:
Yes, the cell membrane in a plant cell can be observed even before adding a salt solution. The cell membrane is a thin, semi-permeable membrane that encloses the cell and separates the cytoplasm from the external environment. It can be visualized using various microscopic techniques such as light microscopy or electron microscopy. However, without staining or specific visualization methods, the cell membrane may not be easily distinguishable from other cell components under regular light microscopy. To enhance its visibility, techniques such as staining with dyes or using specific membrane markers can be employed.
