Q

How does distance affect the rate of diffusion

A

The shorter the distance, the faster the rate of diffusion as the particles do not need to travel as far

Q

How does temperature affect the rate of diffusion

A

The higher the temperature, the higher the amount of kinetic energy a cell has, the higher the probability of it colliding with other particles, the faster the rate of diffusion.

Q

What is active transport

A

Movement of particles from a oow concentration to a high concentration. Is an active process which require energy from respiration from the cells. Is a selective process and uses transport proteins

Q

What is diffusion

A

The random movement of particles from a high concentration to a low concentration. It is a passive process and requires no energy from the cell.
