Chapter 5, Problem 23RQ
a.
Summary Introduction
Introduction: The movement of the solvent or water from a region of low solute concentration to a region of high solute concentration through a plasma membrane is known as osmosis.
b.
Summary Introduction
Introduction: In osmosis, the solvent moves from a region of low solute concentration to a region of high solute concentration. The solution which has more solutes than the other solution is known as a hyperosmotic solution. The osmolarity of NaCl is higher than the osmolarity of the glucose.

A cell with a total of 0.3 osmol/L is placed into a solution with a total of 0.2 osmol/L. It is assumed that the osmotic particles cannot pass through the cell membrane.
Answer the following true or false questions.
1. All particles will diffuse down a concentration gradient, that is, move from a high concentration into a lower concentration
2. Diffusion down a gradient happens because particles are constantly moving (Kinetic Theory)
3. When solvent particles move down a gradient through a membrane it is called osmosis
