Topic 2 - Cell Transport Flashcards
1
Q
What is osmosis
A
Movement of water molecules from an area of high concentration to an area of low concentration
2
Q
What is diffusion
A
The movement of molecules from an area of high concentration to an area of low concentration through a semi permeable membrane
3
Q
What is active transport
A
Molecules move from low to high concentration across a concentration gradient requiring an input of energy
4
Q
What are the differences between active transport and diffusion
A
Active transport requires energy
Active transport is the reverse, moving from low to high
