Which molecular movements is due to diffusion or osmosis?

Answer: Movement of water molecules in a sugar solution is due to Osmosis while Gaseous from a higher concentration to a lower concentration is due to Diffusion.

Explanation:

Osmosis is a process by which molecules move through a semipermeable membrane from a less concentrated region to a more concentrated region.

Example: Movement of water molecules in a sugar solution moves through a semipermeable membrane from a region of lower concentration to a region of higher concentration.

Diffusion movement of molecules from a region of higher concentration to a region of lower concentration. Diffusion is wholly driven by a gradient in the concentration. Diffusion is a very vital and important process for all living organisms via the movement of substances in and out of the cells.

Examples: Gases diffuses from a higher concentration to a lower concentration.

Answer: A process where plant cell is placed on salt water, water moves out of the cell, is a molecules movement of diffusion/osmosis.
