Transportation Flashcards
1
Q
Active transport
A
Net movement of particles for low to high concentration
Against the concentration gradient so energy from respiration is needed
2
Q
Osmosis
A
Movement of water from a high water concentration to a low water concentration through a partially permeable membrane
Passive transport so no energy is required
Along the concentration gradient
3
Q
Diffusion
A
The net movement of particles from a high to low concentration
Along the concentration gradient
4
Q
How to calculate net movement of particles
A
Particles moving in - particles moving out
5
Q
Xylem
A
Transpiration
6
Q
Phloem
A
Translocation
7
Q
Example of diffusion in the body
A
Oxygen diffuses from the lungs to the blood to be taken around the body
