Question

Diffusion can take place in an open system or across a membrane that separates two systems.

• A. True
• B. False

Answer 1

The correct option is B False

Diffusion is defined as the movement of molecules from an area of higher concentration of the molecules to an area of lower concentration of the molecules. For example: If you leave a bottle of cologne open and later notice its fragrance across the room, it is because the aromatic molecules in the cologne have diffused from where they are more concentrated (in the bottle) to where they are less concentrated (across the room).
Water and minerals from the soil move into the cell wall of a plant cell through the simple process of diffusion. So diffusion can take place in an open system or across a membrane.
