Cell Transport - Diffusion

Question 1

diffusion

Answer 1

• Process by which molecules move from areas of high concentration to areas of low concentration
• This does NOT require energy
• Examples:
• Food coloring in the beaker or water
• Air freshener in a room
• Depends on random particle movement.
• More collisions where there is more solute and that will increase movement because of many collisions.

Question 2

concentration

Answer 2

• Mass of the solute in a given volume of solution or mass/volume
• Expressed as g/L or equivalent​
