Diffusion And Active Transport

Question 1

What is diffusion affected by

Answer 1

Surface area
Difference in concentration
Distance
Temperature

Question 2

How does surface area affect the rate of diffusion

Answer 2

The larger the surface area, the faster the rate of diffusion

Question 3

How does the concentration difference affect the rate of diffusion

Answer 3

The larger the difference in concentration, the faster diffusion occurs

Question 4

How does distance affect the rate of diffusion

Answer 4

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

Question 5

How does temperature affect the rate of diffusion

Answer 5

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.

Question 6

What is active transport

Answer 6

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

Question 7

What is diffusion

Answer 7

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.
