Cell Transport

Front

What structure controls the cellular traffic of the cell?

Back

Cell Membrane

Front

During osmosis, what direction does water move?

Back

Water moves from high to low concentration.

Front

What is true about active transport?

Back

It requires energy.

Front

Define Selective Permeability.

Back

The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

Front

What happens to an animal cell placed in a hypertonic (salty) solution?

Back

It shrinks - gets smaller.

Front

What is the primary function of the cell membrane?

Back

To regulate what enters and exits the cell.

Front

What is diffusion?

Back

The movement of molecules from an area of high concentration to an area of low concentration.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to the inside of the cell.

Front

What occurs during facilitated diffusion?

Back

Molecules move across the cell membrane with the help of transport proteins.
