Front

What is the process called when particles move from regions of higher density to regions of lower density?

Back

Diffusion

Front

Which of the following is NOT a characteristic of diffusion: It moves large particles like a giant boulder or it moves small particles like oxygen?

Back

It moves large particles like a giant boulder.

Front

What term describes the movement of substances through a cell membrane without the use of cell energy?

Back

Passive transport

Front

Which statement is NOT true about diffusion: It requires energy or it occurs spontaneously?

Back

Requires energy.

Front

What is the primary difference between active transport and passive transport?

Back

Active transport requires energy, while passive transport does not.

Front

What type of transport involves the movement of water across a selectively permeable membrane?

Back

Osmosis.

Front

What is the role of ATP in cellular processes?

Back

ATP provides energy for various cellular functions, including active transport.

Front

What is the concentration gradient?

Back

The difference in concentration of a substance between two areas.

Front

What happens to a cell in a hypertonic solution?

Back

The cell loses water and may shrivel.
