Cell Transport Homework Flashcardizz

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a semi-permeable membrane from a region of low solute concentration to a region of high solute concentration.

Front

What happens to a cell in a high salt concentration solution?

Back

The cell will shrink due to the loss of water as it moves out of the cell to balance the solute concentration.

Front

How do particles move in diffusion?

Back

Particles move from a region of high concentration to a region of low concentration until equilibrium is reached.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from an area of high concentration to an area of low concentration.

Front

What does semi-permeable mean?

Back

Semi-permeable refers to a membrane that allows only certain particles to cross into or out of the cell.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy.

Front

What is an isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is the same inside and outside the cell, resulting in no net movement of water.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy.

Front

What is the role of the cell membrane?

Back

The cell membrane controls what enters and exits the cell, maintaining homeostasis.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment.
