Osmotic Pressure

Front

What is the process by which particles tend to move from an area where they are more concentrated to an area where they are less concentrated?

Back

Diffusion

Front

What is the process of diffusion in which molecules pass across the membrane through cell membrane channels?

What is the name of the water channel protein in a cell?

Back

Aquaporin

Front

What is the term for the movement of water across a selectively permeable membrane?

Back

Osmosis

Front

What is the difference between passive transport and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What is the role of a selectively permeable membrane in cell transport?

Back

It allows certain substances to pass while blocking others, thus regulating the internal environment of the cell.

What is the term for the concentration of solute in a solution?

Back

Solute Concentration

Front

What is the effect of hypertonic solutions on cells?

Back

Cells lose water and may shrink due to osmosis.
