Passive Transport

Front

What is Passive Transport?

Back

The movement of substances across a cell membrane without the use of energy by the cell.

Front

What is Equilibrium in the context of cells?

Back

A state where the concentration of substances is equal inside and outside the cell.

Front

Define Diffusion.

Back

The process by which molecules move from an area of high concentration to an area of low concentration.

Front

What is Selective Permeability?

Back

The ability of the cell membrane to allow some substances to pass through while blocking others.

Front

What regulates what enters and leaves a cell?

Back

The Cell Membrane.

Front

Can diffusion occur in both plants and animals?

Back

Yes, diffusion can occur in both plants and animals.

Front

What is Osmosis?

Back

The diffusion of water molecules through a selectively permeable membrane.

Front

What happens to a cell in a hypertonic solution?

Back

The cell loses water and may shrink.

Front

What happens to a cell in a hypotonic solution?

Back

The cell gains water and may swell or burst.

Front

What is the role of the cell membrane in passive transport?

Back

It acts as a barrier that selectively allows certain substances to pass through.
