Water Potential and Osmosis

• Out of the cell

• Into the cell

• Both into and out of the cell

• Neither into nor out of the cell

• Into the cell

• Out of the cell

• No net flow of water

• 0.64 net flow of water out of the cell

• -0.36 net flow of water into the cell

• 8.17 net flow of water out of the cell

• -8.83 net flow of water into the cell

In the context of osmosis, what does the term "isotonic" mean?

• The solution has a higher solute concentration than the cell

• The solution has a lower solute concentration than the cell

• The solution has the same solute concentration as the cell

• The solution has no solutes

What role do aquaporins play in osmosis?

• They actively pump water molecules across the membrane

• They block water from entering the cell

• They facilitate the rapid movement of water across the cell membrane

• They transport ions across the membrane

The water will go (a)   .

• Into the cell

• Out of the cell

• Equally in & out - it's isotoni

• There is no water

What is the primary driving force behind osmosis?

• Active transport

• Concentration gradient

• ATP energy

• Temperature

Which of the following best describes osmosis?

• Movement of solutes from high to low concentration

• Movement of water from low to high solute concentration

• Movement of water from high to low solute concentration

• Movement of solutes using energy

Osmosis

• diffusion of water molecules through a semi-permeable mebrane from an area of low concentration to an area of high concentration

• the diffusion of particles from an area of high concentration to an area of low concentration

• diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration

• the diffusion of particles from an area of low concentration to an area of high concentration
