Importance of selectively permeable membrane
Witryna22 lut 2024 · A cell needs a selectively permeable membrane in order to maintain a balance of water in the cell and the ability to bring in glucose and other items it needs … Witryna24 wrz 2024 · Selective permeability is an essential feature of the plasma membrane. Without it, the cell would be unable to control the molecules entering and leaving the cell. This would disrupt the cell’s normal functioning, leading to a malfunctioning cell and eventually cell death.
