Cell transport

Question 1

What is diffusion?​

Answer 1

Form of passive transport, movement from high concentration to low concentration.​

Question 2

What is osmosis?​

Answer 2

Passive transport, but water, goes through selective permeable membrane, from high concentration to low concenration.

Question 3

What is passive transport?​

Answer 3

Doesent require energy.​

Question 4

What is active transport?​

Answer 4

Active transport, dosent require energy, comes from ATP, against concentration gradient.​

Question 5

What is the method of investigating osmosis?​

Answer 5

Cut identical potato using cork borer, measure and record length, and mass, add to each cylinder of 1m sugar, 0.5m of sugar, and distillate water, leave cylinders overnight, remove from tubes and blot using paper towel, record length and mass, draw graph.​
