* Cell membrane (plasma membrane): This membrane surrounds every individual cell and controls the movement of substances into and out of the cell.
* Tonoplast (vacuolar membrane): This membrane surrounds the central vacuole, which is a large, fluid-filled organelle found in plant cells. The tonoplast regulates the movement of substances into and out of the vacuole.
* Mitochondrial membrane: This membrane surrounds the mitochondria, the powerhouses of the cell. It plays a role in cellular respiration and energy production.
* Chloroplast membrane: This membrane surrounds the chloroplasts, the organelles responsible for photosynthesis. It regulates the movement of substances into and out of the chloroplast.
Therefore, selectively permeable membranes are essential for all plant cells to maintain their internal environment and carry out vital functions.
