Cholesterol is one of the major lipid components of the plasma membrane of mammalian cells.
The electrode tip pushes through the cell wall tending to jump quickly across the plasma membrane into either the cytoplasm or the vacuole.
This indicates the firm appression of the plasma membrane to the cell wall, which is typical of a turgescent cell.
