Cell Transport

Front

What happens to eggplant cells when salt is poured on them?

Back

Water will move out of the eggplant cells and the cells will shrink.

Front

What cell structure controls what substances may enter or leave cells?

Back

Cell membrane.

Front

What is the process called when particles too large to enter the membrane need help from channel proteins without using energy?

Back

Facilitated diffusion.

Front

What is the definition of Selective Permeability?

Back

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

Front

What process allows water to move into root cells of a plant when the concentration of water is higher in the soil?

Back

Osmosis.

Front

What is the main function of the cell membrane?

Back

To maintain homeostasis by controlling the movement of substances in and out of the cell.

Front

What is passive transport?

Back

The movement of materials across the cell membrane that requires no energy from the cell.

Front

What is active transport?

Back

The movement of materials against a concentration gradient, requiring energy.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is the difference between facilitated diffusion and simple diffusion?

Back

Facilitated diffusion requires channel proteins, while simple diffusion does not.
