Diffusion
|
the movement of particles from an area of higher concentration to lower concentration
DOES NOT REQUIRE ENERGY |
|
|
Selectively Permable Membrane
|
only allows certain particles to pass through
|
|
|
Osmosis
|
the diffusion of water from a high concentration to a low concentration
|
|
|
Osmosis in Cells
|
contains lots of sugar, proteins
gain water until water concentration outside and inside are the same |
|
|
Active Transport
|
moves molecules from a high concentration to a low concentration
REQUIRES ENERGY! |
|
|

them____(PRED.DV)_____ because____(evidence)____ |
|
|
Conclusion
|
Claim- Result
Evidence-Data (CS!) Reasoning- Support, explain |
|
|
Passive Transport
|
Diffusion & Osmosis
high to low concentration no energy required small and uncharged molecules |
|
|
Active Transport
|
low to high concentration
energy is required small or large molecules charged or uncharged molecules |
|
|
Facilitated Diffusion
|
high to low concentration
no energy is required large and charged molecules use protein channels in cell membrane |
|
|
Endocytosis/Exocytosis
|
energy required
very large molecules cell membrane endocytosis- brings in exocytosis- releases out |
