What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
What is the movement called when a call does not use energy to move particles across the cells membrane?
It is called passive diffusion.
Which term describes the movement of water molecules into and out of the cell?
Osmosis is the movement of water particles from an area of high concentration to an area of low concentration, across a semi-permeable membrane.
Where is the net movement of water in a hypotonic solution?
no Water will move freely between the two solutions if they are separated by a selectively permeable membrane. However, there will be no net change in the concentration of water on either side of the membrane. Differences in solute concentration will allow you to predict net changes in water movement.
How do cells use the process of osmosis and diffusion to take in nutrients and to get rid of wastes?
== == Diffusion is: the movement of particles from regions of higher concentration to regions of lower concentration. Osmosis is: the diffusion of water through a semipermeable membrane.
How do particles get in and out of the plasma membrane?
The movement is random, but there is a net movement from regions where there are lots of particles to ones where there are fewer particles.
Diffusion is the movement of a sustance?
Diffusion is the movement of particles in a substance through a semi permeable membrane. Osmosis is similar but only involves water particles passing through a semi permeable membrane.
In osmosis which membrane provides net movement of water without movement of NaCl?
Osmosis across a selectively permeable membrane allows water across but disallows other particles across the membrane.
What are the characteristics of a osmosis?
osmosis is the net movement of particles through a partially permeable membrane.
The movement of water across a membrane is termed?
it is called osmosis and it is the net movement of water particles across a semi-permable membrane against the concentration gradient!
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
The movement of relatively large particles across a plasma membrane via transport proteins?
... is called "facilitated diffusion".
What is the movement called when a cell does not use energy to move particles across the cell's membrane?
It is called passive diffusion.
What is the movement called when a call does not use energy to move particles across the cells membrane?
It is called passive diffusion.
What does osmosis require?
Osmosis is the movement of particles from a high concentration to a low concentration accross a partially permeable membrane.
What is the movement of relatively large particles across a plasma membrane via transport proteins called?
Facilitated Diffusionosmosis & diffusion
What is osmosis function?
This is the movement of water particles from an are of high concentration to an area of low concentration through a partially permeable membrane.
