Question 2

Active transport

Answer 2

• energy driven
• the cell wants the molecules so it pulls them in
• when it opens up the semi permeable membrane to get those things it would leak the good stuff so it uses energy to pull the molecules in against the concentraion gradient

Question 3

Passive transport

Answer 3

• no energy
• moving molecules down concentration gradient
• movement of molecules across cells from an area of higher concentration to lower

Question 4

Osmosis

Answer 4

• movement of solvents through a semi-permeable membrane
• the solvents want to go the the area of higher concentration of soloute so it can balance out

Question 5

Defussion

Answer 5

• movement of particles down the concentration gradient
