exif: {"Image DocumentName": "Water Potential In Potato Cells", "Image ImageDescription": "Osmosis is a special type of diffusion. It is the movement of water molecules through a selectively permeable membrane from a region of higher water potential to an area of lower water potential. Water potential is the measure of free energy of water in a solution. Water always moves to a more negative water potential.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
