thistle funnel
Water should be drawn through the visking tubing by osmosis and this will force the solution up the glass tube (the ________ has an open bottom where the visking tubing goes)
Happens
________ in both liquids and gases- the particles there are free to move about randomly.
Diffusion
________ is the gradual movement of particles from places where there are lots to where there are fewer.
Substances
________ can move in and out of cells via diffusion, active transport, and osmosis.
Water molecules
________ pass both ways through the membrane during osmosis.
Active transport
________ allows nutrients to be taken into the blood, despite the fact that the concentration gradient is the wrong way.
Definition
________: ‘ Active Transport is the movement of particles against a concentration (i.e: from a lower concentration to a higher concentration) using energy released during respiration.
Technical Definition
________: the ‘ net movement of particles from an area of high concentration to an area of low concentration.
Technical definition
________: ‘ Osmosis is the net movement of water molecules across a partially permeable membrane from a high concentration of water to a low concentration of water.
tissue fluid
The ________ will usually have a different concentration to the fluid inside a cell.
Active transport
________ is used to move substances in and out of cells.
