Cell Transport

Front

What happens to a cell in a hypotonic solution?

Back

It can swell and burst.

Front

A solution in which the concentration of solutes is the same inside and outside of a cell is called a __________ solution.

Back

isotonic.

Front

If a cell is 90% water and 10% solute, and it is placed in a solution that is also 90% water and 10% solute, what is the nature of the solution?

Back

It is isotonic because the concentration is the same inside and outside the cell.

Front

What is a selectively permeable membrane?

Back

A membrane that allows certain size substances to enter and leave.

Front

What is the function of the Golgi apparatus?

Back

It modifies, sorts, packages, and transports proteins.

Front

What occurs in a hypertonic solution?

Back

Water exits the cell, causing it to shrink.

Front

Define osmosis.

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 diffusion?

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is the role of the cell membrane?

Back

To protect the cell and regulate what enters and leaves.

Front

What is active transport?

Back

The movement of substances against their concentration gradient, requiring energy.
