When does the cell have to use active transport?
Weegy: Some substances cannot pass through diffusion (when particles move from a high concentration to a low concentration), instead the particles are moved by use of energy. [ This is seen in root cells, where the roots absorb some of the mineral salts in the soil, they are absorbed by active transport since they are moved against a concentration gradient. ] (More)

Diffusion is the movement of a substance A. only through the lipid bilayer. B. only in liquids. C. only in air. D. from an area of high concentration to an area of low concentration. User: Diffusion is the movement of a substance
Weegy: Osmosis is the diffusion of water through a semi-permeable membrane, from a solution of low solute concentration (high water potential) to a solution with high solute concentration (low water potential), up a solute concentration gradient. User: The lipid bilayer molecules do what for the cell? User: Which of the following is an example of osmosis? Weegy: Osmosis is the diffusion of water through a semi-permeable membrane, from a solution of low solute concentration (high water potential) to a solution with high solute concentration (low water potential), up a solute concentration gradient. User: Which transport process always involves the movement of materials from inside the cell to outside the cell? User: What is the main function of the cell wall? Weegy: Sir/MAdam, The main function of the cell wall is it KEEPS CELLS TURGIDITY IT ALSO PROTECTS THE CELL. (More)
