Sci2 Intro to Diffusion & Osmosis DO NOW

Front

What is diffusion?

Back

Diffusion is the process by which molecules move from an area of high concentration to an area of low concentration until they are evenly distributed.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is passive transport?

Back

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

Front

What is equilibrium in the context of diffusion?

Back

Equilibrium is the state reached when the concentration of a substance is uniform throughout a space.

Front

What role does a cell membrane play in osmosis?

Back

The cell membrane is selectively permeable, allowing water to pass through while controlling the movement of solutes.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion refers to the movement of any molecules from high to low concentration, while osmosis specifically refers to the movement of water.

Front

What is an example of diffusion in everyday life?

Back

An example of diffusion is the smell of food traveling from the kitchen to the dining room.

Front

What happens to plant cells in a hypotonic solution?

Back

In a hypotonic solution, plant cells swell as water enters, but they do not burst due to the presence of the cell wall.

Front

What happens to plant cells in a hypertonic solution?

Back

In a hypertonic solution, plant cells lose water and shrink, a process known as plasmolysis.

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane allows certain substances to pass through while blocking others.
