How Does Human Activity Affect Rivers? Cell Transport

Front

What is the goal of diffusion called when molecules are equally spread out?

Back

Equilibrium

Front

What happens when the membrane does not allow certain molecules to pass through?

Back

Water will flow into the side with a higher concentration of solute.

Front

What type of solution should ideally surround your cells?

Back

Isotonic solution.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solute compared to the inside of the cell.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will shrink.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solute compared to the inside of the cell.

Front

What happens to a cell in a hypotonic solution?

Back

The cell will swell up.

Front

Define osmosis.

Back

The movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

Front

What is facilitated diffusion?

Back

The process of transporting substances across a cell membrane with the help of carrier proteins, without using energy.
