The Cell in Action - Section 1

Question 1

The movement of particles from an area where their concentration is high to an area where their concentration is low.

Answer 1

diffusion

Question 2

The diffusion of water through a cell membrane.

Answer 2

osmosis

Question 3

The diffusion of particles through proteins in the cell membrane, from areas of high particle concentration to areas of low particle concentration.

Answer 3

passive transport

Question 4

The movement of particles through proteins in the cell membrane against the direction of diffusion; requires cells to use energy.

Answer 4

active transport

Question 5

The process in which a cell membrane surrounds a particle and encloses it in a vesicle to bring it into the cell.

Answer 5

endocytosis

Question 6

The process used to remove large particles from a cell; during this process, a vesicle containing the particles fuses with the cell membrane.

Answer 6

exocytosis
