NGSS.HS-LS1-3

A difference in the concentration of a substance across a distance

• Concentration Gradient

• Osmosis

• Facilitated Diffusion

• Active Transport

Requires NO energy, Movement of molecules from High to Low concentration, Moves with the concentration gradient

• Osmosis

• Active Transport

• Hypotonic

• Passive Transport

Movement of molecules from an area of higher concentration to an area of lower concentration.

• Active Transport

• Diffusion

• Passive Transport

• Osmosis

Diffusion of Water across a selectively permeable membrane

• Osmosis

• Passive Transport

• Active Transport

• Facilitated Diffusion

Movement of specific molecules across cell membranes through protein channels

• Osmosis

• Active Transport

• Facilitated Diffusion

• Passive Transport

A solution with the same concentration of water and solutes as inside a cell, resulting in the cell retaining its normal shape because there is no net movement of water.

• Isotonic

• Hypertonic

• Hypotonic

solute concentration is greater than that inside the cell; cell loses water

• Isotonic

• Hypotonic

• Hypertonic
