Take a look at the following animation; If a selectively permeable membrane separates the two solutions‚ water moves through it in both directions at the same

can diffuse across cell membranes while some substances must be transported across the membrane by proteins. The membrane is in control of what enters and leaves the cell. However‚ certain conditions may damage the cell membrane’s structure. Beet cells‚ which are plant cells‚ have a water-soluble pigment called betacyanin‚ which is stored in its vacuole. The tonoplast‚ or the vacuole’s membrane‚ acts with the cell membrane of the cell to prevent the betacyanin
