Transport

Question 1

What is diffusion?

Answer 1

Movement of particles from an area of high concentration to an area of low concentration.
It continues until an equilibrium is reached

Question 2

What are the factors that increase diffusion?

Answer 2

Temperature
Surface area
Concentration gradient

Question 3

How does concentration gradient increase diffusion?

Answer 3

The larger the concentration gradient the more the particles in the crowded area would want to get to the less busy area

Question 4

How does temperature increase diffusion?

Answer 4

It means the particles move around quicker.making diffusion take place more rapidly.

Question 5

How does surface are increase diffusion

Answer 5

It allows absorption to happen quickly and effectively. Gives more space for particles to pass through.

Question 6

What is isotonic?

Answer 6

The concentration of solutes in the solution outside the cell is the same as the internal concentration.

Question 7

What is hypertonic?

Answer 7

If the concentration of solutes in the solution outside the cell is higher than the internal concentration.

Question 8

What is Hypotonic

Answer 8

If the concentration of solutes in the solution outside the cell is lower than the internal concentration

Question 9

Plasmolysis

Answer 9

If more water is lost by osmosis, the vacuole and cytoplasm shrink and eventually the cell membrane pulls away from the cell wall.

Question 10

What is osmosis

Answer 10

a process by which molecules of a solvent tend to pass through a partially permeable membrane from a less concentrated solution into a more concentrated one.

Question 11

What is active transport?

Answer 11

Active transport moves substances from a more dilute solution to a more concentrated solution (against a concentration gradient
