Cell Transport

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What are the two types of passive transport?

Back

The two types of passive transport are osmosis and diffusion.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules across a selectively permeable membrane.

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.

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 happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water enters the cell, which can cause the cell to swell and potentially burst.

Front

What is an 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 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 happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water leaves the cell, which can cause the cell to shrink.
