Cell Membrane and Transport

Front

What is 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 process allows water to move into plant root cells when the concentration of water is higher in the soil?

Back

Osmosis

Front

During osmosis, water moves from:

Back

High concentration to low concentration.

Front

What is Active Transport?

Back

The movement of solutes against the concentration gradient from a low concentration to a high concentration, requiring energy.

Front

What structure controls the cellular traffic of the cell?

Back

Cell Membrane.

Front

What is the primary function of the cell membrane?

Back

To regulate what enters and exits the cell.

Front

Define Osmosis.

Back

The diffusion of water across a selectively permeable membrane.

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 Simple Diffusion?

Back

The movement of molecules from an area of high concentration to an area of low concentration without the use of energy.

Front

What is the role of proteins in the cell membrane?

Back

Proteins assist in the transport of substances across the membrane and play a role in cell signaling.
