Increasing sucrose concentrations causes the osmotic concentrations of disks of potato tubers to decrease. Abstract: Introduction: Biological membranes are composed of phospholipid bilayers, with each phospholipid having hydrophilic heads and hydrophobic tails, as well as proteins. This arrangement of proteins and lipids produces a selectively permeable membrane. Many kinds of molecules surround or are contained…
