Diffusion & Osmosis

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

During osmosis, what direction does water move?

Back

Water moves from high to low concentration.

Front

What is 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

What is diffusion?

Back

Diffusion is when molecules move 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

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 energy of molecules, leading to faster diffusion.

Front

What is the difference between osmosis and diffusion?

Back

Osmosis specifically refers to the movement of water, while diffusion refers to the movement of any type of molecules.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, causing it to swell and potentially burst.
