DIFFUSION flashcard

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration.

Front

What regulates what enters and leaves a cell?

Back

The Cell Membrane regulates what enters and leaves a cell.

Front

Which diagram best shows the end result of diffusion?

Back

Diagram J best shows the end result of diffusion.

Front

What is the definition of Selective Permeability?

Back

Selective Permeability is the ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

Front

Where is there a high concentration of water?

Back

There is a high concentration of water in the vase.

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 factors affect the rate of diffusion?

Back

Factors affecting the rate of diffusion include temperature, concentration gradient, and the size of the molecules.

Front

What is a semi-permeable membrane?

Back

A semi-permeable membrane is a barrier that allows certain substances to pass through while blocking others.

Front

How does temperature affect diffusion?

Back

Higher temperatures increase the kinetic energy of molecules, leading to a faster rate of diffusion.

Front

What is the concentration gradient?

Back

The concentration gradient is the difference in concentration of a substance between two areas.
