Match the following

• Passive Transport

• Movement of Water from High to Low Concentration across a semi-permeable membrane.

• Facilitated Diffusion

• Movement of molecules across a plasma membrane by means of Protein Channel.

• Diffusion

• Movement of molecules from High to Low. It moves without assistance through the membrane.

• Osmosis

• Type of transport that does not require energy to move substances across cell membranes.

112.34.c.4.B

Select the type of solution in which the concentration of solute molecules is balanced on both sides of the membrane.

Tags

112.34.c.4.B

Select the type of solution where the external environment contains more water than inside the cell causing the cell to eventually burst.

Type of Tonicity if a cell is placed in, there will be no net flow of water into or out of the cell, keeping the cell the same shape and size.

Tags

112.34.c.4.B

Type of Tonicity if a cell is placed in, there will be a net flow of water out of the cell, the cell will lose volume, and shrink in size.

Tags

112.34.c.4.B

Type of Tonicity if a cell is placed in, there will be a net flow of water into the cell, the cell will gain volume, and swell until the cell bursts or becomes turgid.
