The process of diffusion requires:

A. light energy
B. non-permeable membrane
C. semi-permeable membrane
D. no membrane

Answer :

Final answer:

Diffusion is the movement of molecules from high to low concentration and does not require any energy or a membrane. While it can occur across a semi-permeable membrane, it can also take place in an open environment. Therefore, the correct answer is that diffusion requires no membrane.


Explanation:

Understanding Diffusion


Diffusion is the process by which molecules move from an area of high concentration to an area of low concentration. This movement occurs spontaneously and does not require any energy input or a membrane to facilitate the process.


To clarify the options presented in your question:



  1. Light energy: Diffusion does not require light energy; it occurs naturally due to the kinetic energy of the molecules.

  2. Non-permeable membrane: A non-permeable membrane would block the movement of molecules, thus diffusion cannot occur through it.

  3. Semi-permeable membrane: While diffusion can occur across a semi-permeable membrane, it is not necessary for the process itself, as diffusion can also happen in open spaces.

  4. No membrane: Correct choice. Diffusion can occur without the presence of any membrane.


In conclusion, the correct option is that diffusion can occur without a membrane. This means diffusion can take place even in an open environment, driven solely by the concentration gradient of the molecules involved.
