Science quiz on moving molecules Flashcards
Osmosis
When water molecules diffusing through a selectively permeable membrane.
Diffusion
Molecules moving from high to low concentration of molecules.
Passive transport
Doesn’t require cells energy and is done by diffusion
Active transport
Uses energy because the cell needs more than the equilibrium of molecules
Low to high concentration of the opposite
high to low concentration
Do cells get everything from their environments?
yes
Blood
Where cells hang out
Cell Membrane
Is selectively permeable and controls what goes in and out
Selectively Permeable
choosing what goes in and out
Equilibrium
A balance of molecules in places
Why did the salt water Potato become more flexible
It became more flexible because the water travled out of it because the water molecules like the salt.
Why did the water potato become harder
