Into and Out of the Cell WS Key
Each of the boxes below represents a different method cells use to bring small particle into the cell or to take small particles out of the cell. Add the notes at the bottom of the pate to the appropriate box. Be careful—some notes can be used more than once.
Osmosis / Passive Transport / Active Transport-Particles move through cell membrane between phospholipid molecules
-Particles move from an area ofhigh concentration to an area of lowconcentration
**Water
-Does not require ATP
#2, 5, 6, and 8 / -Particles move through protein doorways
-Particles move from an area of high concentration to an area of low concentration
-Sugar or amino acids
-Does not require ATP (energy)
# 1, 3, 5, and 6 / -Particles move through protein doorways
-Particles move from an area of low concentration to an area of highconcentration
**Requires ATP
#1, 4, and 7
Notes:
- Particles move through protein doorways

- Water
On the back of this page DEFINE:
-Diffusion—movement of particles where their concentration is high to an area where there concentration is low
-Osmosis—the diffusion of water across a cell membrane
-Passive Transport --the diffusion of particles through proteins in the cell membrane from areas where the concentration of particles is high to areas where the concentration of particles is low
-Active Transport--the movement of particles through proteins in the cell membrane against the direction of diffusion. Requires cells to use energy, ATP
