Question

Which of the following statements is true w.r.t both osmosis and diffusion

• A. Occurs in both living and non-living systems
• B. Does not require external energy to drive these processes
• C. Takes place along the concentration gradient.
• D. All of these

Answer 1

The correct option is D All of these

The following statements are true for both osmosis and diffusion.
Occurs in both living and non-living systems - the diffusion of gases in stomata in a plant system. Diffusion of food colouring in water.
Osmosis and diffusion do not require external energy to drive these process.
Osmosis and Diffusion take place along the concentration gradient. (For diffusion - from an area of high concentration to an area of low concentration.)( for osmosis - molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.)
