Movement of Materials

Question 1

What is passive transport

Answer 1

movement of material across a cell membrane without energy

Question 2

What is diffusion

Answer 2

where molecules of a high concentration move to and area of low concentration and equal out

Question 3

What is osmosis

Answer 3

the diffusion of water molecules through a selectively permeable membrane

Question 4

What is a hypertonic solution

Answer 4

concentration is higher outside than it is inside so the cell will shrivel

Question 5

What is a hypotoinc solution

Answer 5

concentration is lower outside the cell that inside the cell and the cell will pop

Question 6

What is isotonic solution

Answer 6

concentration are the same outside and inside the cell

Question 7

What is facilitated diffusion

Answer 7

like regular diffusion but uses a carrier protein to move materials across the cell membrane

Question 8

What is active transport

Answer 8

energy requiring process that enables materials to move across a cell membrane against the concentration gradient

Question 9

What is endocytosis

Answer 9

taking material into the cell

Question 10

What is exocytosis

Answer 10

taking material out of the cell
