What is the diffusion of water only across a cell or semi-permeable membrane?

• Osmosis

• Diffusion

• Active Transport

• Passive Transport

Diffusion and Osmosis are examples of...

• Active Transport

• Passive Transport

During osmosis

• water moves from high to low concentration

• large or oddly shaped molecules move across a cell membrane

• water moves when energy is used

• proteins are built

Which way will the water molecules move during osmosis?

• Out of the cell, so the cell shrinks.

• Out of the cell, so the cell swells.

• Into the cell, so the cell shrinks.

• Into the cell, so the cell swells.

Osmosis is:

• The movement of water molecules from an area of high concentration to an area of lower concentration through a fully permeable membrane

• The movement of water molecules from an area of high water potential to an area of lower water potential through a semipermeable membrane

• Movement of water from an area of low concentration to high concentration

• A strange word
