To regulate what enters and exits the cell.

Front

Define osmosis in biological terms.

Back

The movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the difference between a hypertonic and hypotonic solution?

Back

A hypertonic solution has a higher solute concentration than the cell, while a hypotonic solution has a lower solute concentration.

Front

What role do ribosomes play in the cell?

Back

Ribosomes are responsible for protein synthesis.

Front
