Cell Transport

Diffusion

High concentration to Low comcentration

does not need energy

What gets through?

small; uncharged

Oxygen

Carbon Dioxide

water

Osmosis

High concentration to Low concentration

does not need energy

requires a transport protein

What can get through?

Water

Facilitated Diffusion

High concentration to Low concentration

does not need energy

requires a channel protein

Glucose carrier protein

what can get through?

Glucose

equilibrium

isotonic

same concentration

from low concentration to high concentration

requires energy

need protein to transfer molecules

Pumps

Na+/K+ pump

contractile vacuole

protein=ATD(Adenosine Tri Phosphate)

Endocytosis

eat outside cells through membrane

Exocytosis

some inside cells are gotten rid out of membrane

Hypertonic

outside of Chloroplast

Higher concentration than the area compared

Hypotonic

inside of Chlorolast

lower concentration than the area compared
