Cell Membrane transport: Passive

Because it controls the movement of substances in and out of the cell

Because it provides energy to the cell

Because it stores genetic information

Because it produces proteins

Phospholipids, proteins, carbohydrate chains

DNA, RNA, ribosomes

Chlorophyll, mitochondria, lysosomes

Cell wall, cytoplasm, nucleus

Passive transport moves substances from high to low concentration.

Active transport requires chemical energy like ATP.

Passive transport requires chemical energy.

Active transport moves substances against the concentration gradient.

To the inside of the cell.

To the outside of the cell.

The molecules will move in and out because they are at equal concentrations.

The molecules will not move.

Facilitated diffusion

Osmosis

Active transport

Simple diffusion

Osmosis is the movement of water across a semipermeable membrane.

Osmosis requires chemical energy to occur.

Osmosis involves the movement of solute molecules only.

Osmosis moves water from low to high concentration.

High to Low Concentration

No chemical energy required

Along the gradient

Against the gradient

Phospholipids, proteins, and carbohydrate chains

DNA and RNA

Mitochondria and ribosomes

Cell wall and nucleus
