Phospholipids- are composed of hydrophilic heads and hydrophobic tails, because of their
Phospholipid bilayer- "The hydrophilic phosphate regions interact with the water inside and outside of the sphere. The fatty acids of the phospholipids interact and form a hydrophobic center of the bilayer."
Glycolipid- a lipid with a carbohydrate attached. Its role is cell to cell recognition.
Glycoprotein- a protein with a carbohydrate attached also is responsible for cell to cell recognition.
Aquaporin- are proteins embedded in the cell membrane that allows water to flow through the membrane into the cell, or vise verse.
Water Potential- "The physical property predicting the direction in which water will flow, governed by solute concentration and applied pressure." (Water potential =pressure potential + solute potential)
Solute Potential- "The effect of solute concentration. Pure water at atmospheric pressure has a solute potential of zero. As solute is added, the value for solute potential becomes more negative. This causes water potential to decrease also. In sum, as solute is added, the water potential of a solution drops, and water will tend to move into the solution."
Osmotic Potential- the part of water potential that takes into account the solutes concentration.
Transport Protein- Proteins that are embedded in the cell membrane that aid small molecules into cell.
Concentration Gradient- comparing a certain substance in two different environments (concentration)
