Cell Transport

Front

What process occurs when WATER diffuses across a membrane?

Back

osmosis

Front

high concentration area

Back

Tightly packed together

Front

When particles move from areas of high concentration to areas less concentrated, this has taken place.

Back

diffusion

Front

Why is diffusion and osmosis important to cells?

Back

It allows them to take in materials without using energy.

Front

Selectively-permeable

Back

The cell controls what passes in and out of the cell

Front

What is diffusion?

Back

when molecules move from a high concentration to a low.

Front

Where is there a low concentration of dye? Options: at the bottom of cup, in the color, at the top of cup, no concentration gradient

Back

at the bottom of cup

Front

During osmosis, what happens?

Back

water moves from high to low concentration

Front

Permeable

Back

things can pass through

Front

Movement of particles from high to low concentration.
