What is Diffusion?

Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding

Success Criteria:	You will show your learning by...
Particles in a fluid are always moving. Diffusion is the movement of a substance from a region of higher concentration to a region of lower concentration. Concentration is the number of a particular type of particle in a volume of space. Horizontally, half the particles will be moving to the left and half to the right. Half of a large number is more than half of a smaller number. So more particles will travel from a larger number of particles (high concentration), than are replaced by the smaller number moving form the smaller number of particles (lower concentration). Diffusion happens fastest when: - there is a large surface area - there is a large difference in concentration - there is a short distance between areas of differing concentration. - at higher temperatures. Glucose diffuses into a muscle cell, because there is a higher concentration of glucose particles in the blood than the cell. Oxygen diffuses into a muscle cell, because there is a higher concentration of oxygen particles in the blood than the cell. Carbon dioxide diffuses out of a muscle cell, because there is a higher concentration of Carbon dioxide particles in the cell than the blood. Water diffuses out a muscle cell, because there is a higher concentration of oxygen particles in the blood than the cell. Diffusion occurs through the cell membrane, because there are small gaps in the me. Partially-permeable allows certain particles through but not others. These small gaps allow smaller molecules through but not larger ones. This means the membrane is partially-permeable

AFL/Key Questions:

Describe what particles do in a fluid.
Particles in a fluid are always moving.
What is diffusion?
Diffusion is the movement of a substance from a region of higher concentration to a region of lower concentration.
What is concentration?
Concentration is the number of a particular type of particle in a volume of space.
How do the random movement of particles result in the movement from a higher concentration to a lower concentration?
Half of a large number is more than half of a smaller number. So more particles will travel from a larger number of particles (high concentration), than are replaced by the smaller number moving form the smaller number of particles (lower concentration).
Under what conditions does diffusion happen faster?
Diffusion happens fastest when: - there is a large surface area - there is a short distance between areas of differing concentration. - at higher temperatures.
Why does glucose diffuse into muscle cells from the blood?
Glucose diffuses into a muscle cell, because there is a higher concentration of glucose particles in the blood than the cell.
Why does oxygen diffuse into muscle cells from the blood?
Oxygen diffuses into a muscle cell, because there is a higher concentration of oxygen particles in the blood than the cell.
Why does carbon dioxide diffuse out of muscle cells into the blood?
Carbon dioxide diffuses out of a muscle cell, because there is a higher concentration of Carbon dioxide particles in the cell than the blood.
Why does water diffuse out of muscle cells into the blood?
Water diffuses out a muscle cell, because there is a higher concentration of oxygen particles in the blood than the cell.
How can diffusion occur in and out of cells.
Diffusion occurs through the cell membrane, because there are small gaps in the membrane.
What does partially-permeable mean?
Partially-permeable allows certain particles through but not others.permeable..
Why is the cell membrane referred to as partially-permeable?
The small gaps allow smaller molecules through but not larger ones. This means the membrane is partially-
