Cell Transport

Back

Moving materials in and out of cells

Front

Role of the cell membrane in transporting materials

Back

The cell membrane regulates the movement of substances in and out of the cell.

Front

Basic structure of the cell membrane

Back

phospholipid bilayer with embedded proteins.

Fluid Mosaic Model

Front

Passive Transport

Back

movement of substances across the cell membrane without the use of energy, WITH the concentration gradient.

Front

Hypertonic Solution

Back

High solute concentration

Water moves out

Cell shrinks

Front

Hypotonic Solution

Back

Lower solute concentration

Water moves IN

Cell swells

Front

Isotonic Solution

Back

Equal concentration of solute inside And outside the cell.

No change/Dynamic equilibrium

Front

Active transport

Back

Requires energy to move substances against their concentration gradient.

Front

Homeostasis

Back

The need of an organism to stay stable by regulating internal conditions.

Front

Dynamic Equilibrium

Back

A state where conditions are not always the same, but stay within a range.
