"Investigating 1 factor that can affect the movement of water across potato cell membranes." Use your investigation to find the cell sap concentration expressed as a molar value. Background info: Osmosis is a special kind of diffusion. It happens when a membrane has tiny hoes in it that let water molecules pass through but stops larger molecules like sugar. A membrane like this is called semi- permeable. When a week solution is separated from a strong one by a semi - permeable membrane, water flows from the weak solution to the strong this diffusion is called Osmosis. Plan: To investigate the effects of osmosis, I am going to perform a safe investigation using slices of potato and 2M sugar solution. I am going to cut the potato into 6 strips using a corer to equal size and shape. I will then cut the ends of the potato of to make sure the strips are...
