Cell Membrane and Cell Transport

Front

What happens to a cell when placed in a solution containing a high salt concentration?

Back

The cell will most likely shrink due to water moving out of the cell to balance the solute concentration.

Front

In an isotonic solution, which way will the water flow?

Back

Water will flow both ways at equal rates, maintaining cell size.

Front

What type of transport is diffusion?

Back

Diffusion is a form of passive transport.

Front

What is an isotonic solution?

Back

An isotonic solution has the same solute concentration inside and outside of the cell.

Front

What does hydrophilic mean?

Back

Hydrophilic means water-loving.

Front

What is the primary function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.

Front

What is the difference between hypertonic and hypotonic solutions?

Back

Hypertonic solutions have a higher solute concentration than the cell, causing it to shrink; hypotonic solutions have a lower solute concentration, causing the cell to swell.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What role do proteins play in the cell membrane?

Back

Proteins in the cell membrane assist in transport, act as receptors, and provide structural support.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy.
