Cell Transport 2

Front

What is equilibrium in the context of cell transport?

Back

Equilibrium is the state when the concentration of particles inside a cell is the same as the concentration of particles outside the cell.

Front

What is passive transport?

Back

Passive transport is the movement of particles from an area of high concentration to an area of low concentration without the use of energy.

Front

What happens to a cell in a hypotonic solution?

Back

A cell will swell and perhaps burst (lyse) in a hypotonic solution.

Front

What is osmosis?

Back

Osmosis is the movement of water across a selectively permeable membrane.

Front

Is osmosis a form of active or passive transport?

Back

Osmosis is a form of passive transport.

Front

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

Back

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

Front

What is a hypotonic solution?

Back

A hypotonic solution is one where the concentration of solutes is lower outside the cell than inside, causing water to enter the cell.

Front

What is a hypertonic solution?

Back

A hypertonic solution is one where the concentration of solutes is higher outside the cell than inside, causing water to leave the cell.

Front

What is isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What role do cell membranes play in transport?

Back

Cell membranes control the movement of substances in and out of the cell, allowing selective permeability.
