In which state of matter are particles most free to move around?
Gas
Solid
Liquid
Solid substances can diffuse.
True
False
Choose which sentence best describes Diffusion.
Diffusion is the controlled movement of particles in a given volume. Particles move from an area of high concentration to low concentration. The higher the temperature, the faster a substance diffuses.
Diffusion is the random movement of particles in a given volume. Particles move from an area of low concentration to high concentration. The higher the temperature, the faster a substance diffuses.

Please give an example of diffusion. You have 3 minutes, and you can look online. Try to find an interesting example.
Choose the correct sentence.
Cell membrane are partially permeable to Oxygen, Carbon Dioxide and other substances.
Cell membranes are freely permeable to Oxygen, Carbon Dioxide and other substances.
Cell membrane are partially permeable to Oxygen and Carbon Dioxide, but they are freely permeable to other substances
Cell membranes are freely permeable to Oxygen and Carbon Dioxide, but they are only partially permeable to other substances.
Diffusion of Oxygen and Carbon Dioxide into a cell will happen on it's own. The cell doesn't need to do anything.
True
False
Please provide a short answer to describe the role of diffusion in photosynthesis.

Why do plants droop (fall over) when they don't have enough water?
Teacher Rickie should give you extra homework this lesson.
Yes
