Cell Transport

Front

What is Cell Transport?

Back

The process by which substances move in and out of cells, maintaining homeostasis.

Front

What is Osmosis?

Back

Diffusion of water through a selectively permeable membrane.

Front

What happens to a cell in a hypotonic solution?

Back

The cell will expand as water moves into it.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will shrink as water moves out of it.

Front

What is Active Transport?

Back

The movement of molecules across a cell membrane against the concentration gradient, requiring energy.

Front

What is Passive Transport?

Back

The movement of molecules across a cell membrane without the use of energy, following the concentration gradient.

Front

What is the role of the cell membrane?

Back

It surrounds the cell and controls what enters and leaves 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 a selectively permeable membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.

Front

What is the effect of drinking salty water on cells?

Back

Cells will shrink due to water moving out to balance the solute concentration.
