A membrane called the tonoplast surrounds each vacuole. The cytoplasm and vacuole is surrounded by the plasma membrane. The function of a cell membrane is to control the movement of material into and out of the cell. The tonoplast does the same job for the vacuole. The two main components of any membrane are proteins and fats. The anthocyanin can only be released and leak out of the cell if the membrane are broken or damaged. The anthocyanin diffuses out of cells. Diffusion - gases move about at random and will move about at random and will move from where they are in high concentration to where they are in lower concentration.
