What Is Passive Transport
the movement of molecules across the cell membrane without using cellular energy
the movement of dissolved molecules into or out of a cell through the cell membrane
when particles move from one area of higher concentration to an area of lower concentration.
Define Homeostasis
diffusion of water
the state of relatively constant internal physical and chemical condition
the nucleus
The net movement of water out of or into a cell produces a force
Homeostasis is one of the least important processes done by the cell membrane.
True
False
Define diffusion
it reglates the movement of molecules and other substances from one side of the membrane to the other.
when molecules block out water
when particles move from one area of lower concentration to an area of higher concentration.
when particles move from one area of higher concentration to an area of lower concentration.
Define Facilitated Diffusion
when particles move from one area of higher concentration to an area of lower concentration.
diffusion of water
the process of diffusion in which molecules pass across the membrane through cell membrane channels.
What happens to small uncharged molecules
They pass through the membrane
They dissolve in the membrane’s lipid environment
What happens to large charged molecules
They pass through the membrane
They dissolve in the membrane’s lipid environment
ions are charged cells
True
False
Define Osmosis
when particles move from one area of higher concentration to an area of lower concentration.
diffusion of water
the process of diffusion in which molecules pass across the membrane through cell membrane channels.
What do aquaporins allow water to do
pass through the membrane
dissolve in the membrane
destroy the membrane
move around the membrane
Define Osmosis Pressure
diffusion of water
the state of relatively constant internal physical and chemical condition
the nucleus
The net movement of water out of or into a cell produces a force
