Diffusion and Osmosis

Question 1

What is Diffusion?

Answer 1

Movement of particles from an area of higher concentration to an area of lower concentration

Question 2

What is osmosis

Answer 2

Diffusion of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration

Question 3

What is a selectively permeable membrane

Answer 3

Only allows certain substances to pass

Question 4

What is concentration gradient

Answer 4

Difference in concentration of a substance in 2 areas

Question 5

What is turgor pressure

Answer 5

Outward pressure that is exerted on a plant cell wall contents when water is taken through osmosis

Question 6

How does concentration gradient affect diffusion

Answer 6

It affects the direction the particles move in

Question 7

How is osmosis important for keeping things alive

Answer 7

Cells need to maintain solute concentrations at a certain level to stay alive and healthy

Question 8

What is diffusion’s role on how living things obtain energy and get rid of waste

Answer 8

The particles diffuse muscle waste (waste is mainly found in muscle cells) Oxygen diffuses from blood cells, once inside the oxygen cell, the oxygen is used to make energy
