diffusion is the kinetic movement of molecules from higher concentration to lower concentration.
"diffusion"
Only indirectly. The part of the cell that regulates the movement of material is the cell membrane, which surrounds the cell.
Is Diffusion the movement of molecules from a greater to a lesser concentration.
diffusion is the movement of materials into cell membranes when the outside of the cell has a higher density than the inside
A cell has to have some thing moving across it or the cell will most certanly die.
movement. In a cell.
Osmosis is the movement of water across the cell membrane or the movement of water through diffusion. :)
Diffusion
The movement of things through the cell would be called diffusion. If it is water we are talking about then it is called osmosis. diffusion and osmosis are examples of inactive transport. Active transport involves specific proteins in the cell that pull material in the cell though the cell membrane.
All the imports and exports of cell moves through plasma membrane by diffusion. Which includes proteins, water, nutrients and the products of the cell. The material in excess amount in or out of the call moves in or out of the by diffusion.
This type of movement is called simple diffusion.
When a gas moves in and out of a cell it is called diffusion.
