Which is true regarding diffusion and osmosis? Question 3 options:

a. Osmosis is a type of diffusion and is specific to water.

b. Osmosis is specific to molecule movement and does not require energy.

c. Diffusion is specific to water movement in cells and requires energy.

Option (A)

Explanation:

Diffusion is defined as the transfer of particles such as ions or molecules from a higher concentration region to a lower concentration region.

Osmosis is a special type of diffusion in which the solvents such as water are allowed to move from a region of higher to a lower concentration through a layer of a semi-permeable membrane. This is an energy-independent process and occurs along the concentration gradient.

Thus, the correct answer is option (A) that is true for both osmosis and diffusion.
